Oil for gearbox, transfer case and axles of VAZ-2107
VAZ-2107 is a rear-wheel drive small car, produced from 1982 to 2012. During the years of the USSR, this car was considered the successor to the outdated family of VAZ-2101, 2102 and 2103 models, on the basis of which it was built. In addition to the 2107 car, the updated line consisted of the 2104 station wagon and the 2105 , which, in comparison with the “top” 2107, had a basic level of equipment. In other words, 2107 is a modified version of 2105 . The sedan competed with Moskvich and IZH cars. In post-Soviet Russia, the VAZ-2107 headed the “classic” family of VAZ cars, which was replaced in 2012 by the LADA Granta.
First generation 2107, 1982-2012
Compared to its predecessor 2105, model 2107 was distinguished by its original design of the radiator grille and rear lights. New front seats and an improved instrument panel with tachometer were also installed. The quality of the interior trim has improved slightly, resulting in more comfort. At various times, the VAZ-2107 engine range consisted of gasoline carburetor engines with a volume of 1.3 and 1.5 liters, as well as a more modern injection engine with a volume of 1.5 liters. For some time, a version with a rotary piston engine was offered. In 2008, a modification appeared with a 73-horsepower 1.6-liter engine equipped with distributed injection. The production of the “Seven” was carried out at the IZH plant until 2012. The total production volume of VAZ-2107 was 3.1 million units, including Egyptian-assembled cars (until 2013).
Rear axle gearbox oil tolerance and viscosity: API-GL-4, 5; SAE 75W-90, 80W-90
Replacement frequency, what oil to fill
According to the manufacturer's regulations, service changes of engine oil on the VAZ 2104 are carried out after 8,000-10,000 kilometers or at intervals of 1 year. But some car owners consider this interval to be a little too high, recommending that it be shortened taking into account operating conditions.
It is recommended to use semi-synthetic with a viscosity of 10W-40 as a lubricant. The following motor oils are most popular among model owners:
- Lada Professional 10W-40
- Lukoil Genesis Advanced 10W-40
- Total Quartz 7000 10W-40
From this list, anyone can choose based on preference, price or love for the brand.
When using this car in winter, you should select oil taking into account the climate zone, as well as the recommendations of AvtoVAZ. Viscosity 5W-40 will allow you to operate the car down to -30°C, and 0W-40 up to -35°C.
If you use motor oil of different viscosities for winter and summer, but of the same brand and manufacturer, then flushing is unnecessary.

When to change the oil in the gearbox and axles of a VAZ 2107
The recommended oil change interval for the gearbox and axles of the VAZ-2107 is from 30 to 40 thousand km, depending on operating conditions. Thus, an early oil change may be required in difficult climatic and road conditions, frequent off-road trips or in traffic jams, which often cause sudden starts and braking, which leads to overheating of the transmission. In such conditions, it is necessary to check the condition of the oil as often as possible, which in a spoiled state has the following signs: cloudiness, blackening, insufficient level, specific odor or thick consistency.
What oil to use for gearboxes and axles
Unoriginal
Before purchasing a suitable oil for the rear axle gearbox of a VAZ-2107, you need to pay attention to several important factors. Firstly, this is the choice of a manufacturer with a good reputation: Mannol, Total, Eneos, ZIC, Castrol, Kixx, etc. Secondly, regarding the type of viscosity: synthetic oil is more fluid, suitable for cars of recent years of production. Accordingly, mineral water or semi-synthetics are recommended for older cars. It has a relatively thick consistency, which means there is less chance of leaks in the presence of microcracks or gaps between contact pairs. Thirdly, when choosing an oil, they also pay attention to the current tolerance indicators API-GL-3, 4 or 5. The higher the indicator, the more oil additives. In the case of a VAZ-2107 with high mileage, you can limit yourself to API-GL-4 approval, and owners of cars from recent years of production can use GL-5. Below are suitable oils for the transfer case, axles and gearbox of the VAZ-2107 sedan.
- Castrol Syntrans Transaxle 75W-90 API-GL-4
- Lukoil Transmission TM-5 GL-5 75W-90.
Semi-synthetics and synthetics
The only drawback of such transmission oil for the VAZ 2107 is the relatively high price compared to ordinary mineral water. On average, a canister costs from 1000 to 1500 rubles. The disadvantages are limited to this, but as for the advantages, these include the high-tech lubricant and the content of additives that reduce wear on transmission elements, extending the service life of the gearbox.
The freezing point of these oils is much lower, so they are suitable for use in severe frosts. You can release the clutch pedal a few seconds after starting the power unit and the gearbox will work normally. The lubricant warms up faster and returns normal fluidity compared to mineral lubricant.
Some say synthetic oil
transmission for VAZ 2107 can squeeze out seals and leak from cracks. This is not true and if this really happens, it is a coincidence, and the real reason is hidden in the obviously worn-out gearbox.

Changing the oil in the rear axle gearbox on a VAZ 2101-VAZ 2107
Welcome! Oil in the gearbox - all the mechanisms that rotate and rub against each other need oil, the same with the gearbox, inside it there are gears (They are metal) that rub against each other during operation and if they are not lubricated with anything, they will quickly come out (They will become scuffed or even deformed and the gearbox will have to be replaced), and when lubricated they will rotate and rub against each other with much less friction and therefore the wear of the parts will be reduced (They will not fail so quickly) , in addition, the gears in the gearbox will also work more quietly and thus it will not hum and vibrate too much as it will if you completely drain the oil and start the car.
Note! To change the oil you need a minimum of tools and a minimum of time, so here are the tools you will need: A wrench of about “17”, and also stock up on a hexagon of about “12”, so you will need a cloth to clean the drain plug from all the dirt, well and the oil itself, by the way, the gearbox contains about 1.3 liters of transmission oil (take a container for draining about 2 liters, or even a basin can be substituted, it’s just not convenient to drain the oil into a small container)!

Where is gearbox ? It is located in the rear central part under the bottom of the car, there is also a cardan transmission (some people call it a driveshaft) passes and is connected to this very gearbox, in the photo below you can clearly see the gearbox since it is circled, there are two more plugs on it are needed just for filling the oil (This is the filler plug indicated by the red arrow) and for draining it (This is the drain plug indicated by the blue arrow), remember them right away because as you read the article, we will not indicate them in the photographs, but simply say, unscrew the filler plug, unscrew the drain, so you need to know their location.
When do you need to change the oil in the rear axle gearbox? There is no specific threshold for changing the oil, since different manufacturers have different quality ones, some claim that the oil never needs to be changed (There are a lot of statements about the fact that the oil does not need to be changed, regarding the steering gear; in fact, everything wears out over time and must be replaced) but each oil has additives, thanks to which the gears wear out less; they also have anti-corrosion properties so that the gears do not rot, so after a certain threshold the oil will have to be changed 100%, as for the rear axle gearbox, the oil in it is replaced 20,000-40,000 thousand km. mileage depending, as we have already said, on the quality of the oil, in addition, you also need to look at the operation of the car (Where it drives), for example, if you live in a rural area where there is only dust and dirty road surfaces on which you have to skid in the rain, then the oil in this case, you need to change it more often, the same applies to cars that drive for a short distance and brake and then drive again (In the city, many cars drive like this, constantly stuck in traffic jams) and the oil becomes unusable most quickly when driving at high speeds ( Because there the engine turns a lot of revolutions) and when pulling various kinds of trailers.
Note! In addition to the above things, the oil also needs to be changed after its expiration date (it is indicated on the box and is equal to approximately five years) since during this time all its properties and additives are lost and the oil can no longer be called oil after that, it just becomes a meaningless liquid , by the way, there are also unscheduled oil changes that must be carried out when buying a used car (Required), immediately after running in a new car (They simply fill new cars with oil that is only enough for a short-term fill, they save so much, and even more so after running in the oil needs to be changed, since all the parts are ground in and during grinding they wear out a little and all their wear needs to be removed by changing the oil) and this also applies to old cars, so if you installed a new gearbox, for example, then after its break-in (2,500-3,000 thousand km) the oil needs to be changed to remove all metal shavings from the new gears (wear products, so to speak)!
By the way, regarding the installation of a new gearbox, if you have replaced it, then after filling the oil, we recommend that you drive it literally 50-100 km and then drain the oil into a clean container and let it sit for a month or two (You need to look at how the dirt completely precipitates turn) and after that it can be filtered and reused, but you need to drain the oil after such a short period of time because inside the new gearbox there will be dust and dirt on its walls, and with a short-term oil change you will remove all this dirt!
Changing the oil in the rear axle of a VAZ-2107
The rear axle gearbox of the VAZ-2107 is a complex device with the help of which crankshaft revolutions are converted into rotation of the rear wheels. The drive axle is fixed to the car body using rods. For reliable operation of the gearbox, a special lubricant is provided, which protects mechanical parts from premature wear. This device operates under large temperature differences and constant high load. Therefore, to protect surfaces, a special oil with enhanced protective properties is required.
The rear axle often operates at high temperatures (about 140 degrees). Under the influence of air, the composition of the lubricating fluid oxidizes, clots and sediment form, and viscosity decreases. As a result, the protective lubricant becomes useless. And the parts of the drive axle are destroyed. Changing the oil in the rear axle of a VAZ-2107 can significantly extend the life of the vehicle.
The design of the VAZ-2107 gearbox is a hypoid gear with offset axes. This structure reduces noise levels during grinding of mechanism parts. But at the same time, additional sliding can cause knots to jam. High-quality lubrication protects against the occurrence of this type of malfunction.
Where is the gearbox located?
On the "sevens", as on all representatives of the rear-wheel drive family, the gearbox is located at the rear, under the bottom of the car. It connects the cardan to the VAZ 2107 axle and causes the wheels of the car to rotate. Rotation occurs thanks to axle shafts engaged in the gearbox, which, due to the technical features of the rear axle of the VAZ 2107, will have to be removed later. If the car is lifted, or when viewed from a garage pit, the gearbox is simply impossible not to notice.
Signs and malfunctions of the classic rear axle gearbox
Replacing a gearbox with your own hands is a labor-intensive process, which includes not only the purchase of a new unit (quite expensive), but also time costs. Therefore, before you start, you need to make sure that the gearbox is faulty. You can define the signs like this:
- gradually accelerating the car, listen carefully and remember at what moment the noise appears;
- while driving, start engine braking (remove your foot from the gas pedal at speed), at this time listen to the gearbox and note the moment the noise appears;
- accelerate the "seven" to hundreds, switch to neutral and turn off the engine - listen to how the gearbox behaves while coasting.
“If the bridge is noisy both in neutral and at speeds, the gearbox has nothing to do with it. If the hum occurs only at speed (regardless of the number), repairs, or, as a last resort, replacement of the gearbox are inevitable.”
When the signs are identified, it is necessary to carry out another check:
- park the car, secure the front wheels with shoes;
- jack up the rear so that the bridge hangs over (it is necessary that the wheels come off the surface);
- start the engine and accelerate the “seven” to the point at which noise occurs, while the wheels should spin without load.
If the noise has not changed, then the gearbox is clearly in good working order and it is not the cause of the trouble. Here other drive units are checked. Well, if there is no noise when driving without a load, then we are talking about worn gears of the gearbox, which make noise only when driving with a load.
The “seven” gearbox itself is a fairly reliable unit that can withstand a period of 100 to 300 thousand mileage, and there is no need to even look into it. Gears, gear spacer, differential adjustment - all these problems arise during improper operation:
- the use of oil with a low viscosity level, as well as failure to comply with the terms of its replacement;
- operating the “seven” with an amount of oil insufficient for this;
- During movement, the bridge is subject to extreme loads (frequent and unsuccessful slips).
Gearbox removal process
In order to repair or replace the rear axle gearbox of a VAZ 2107, you first need to remove it from the car:
- Drain the oil. This, by the way, may be a reason to replace it.
- Separate the flanges of the cardan and gearbox. To do this, you need to unscrew four bolts and nuts. At this time, it is necessary to fix and immobilize the cardan with a screwdriver or by holding the brake pedal. After unscrewing the nuts, you need to tie the cardan to the muffler. You can simply hang it, but this can also lead to negative consequences for the cardan.
- Remove the axle shafts, because without this the gearbox cannot be removed. At the same time, you can inspect the seals, and if they are worn out, replace them. This will save time and prevent possible malfunctions.
- Separate the beam and gearbox by unscrewing all eight bolts that secure it. When unscrewing the latter, it is necessary to hold the gearbox so that it does not fall. The bolts are unscrewed - carefully remove the gearbox.
Repair and adjustment of the VAZ 2107 gearbox
Before you start repairing the gearbox and its subsequent adjustment, you need to have certain skills, backed up by skills, observe all the nuances and subtleties of this process, and also strictly follow the technological nuances of the process. Therefore, if a person starts work for the first time, then it is better to abandon this idea. In addition, you must have all the necessary tools:
- pullers;
- stands;
- a set of keys, screwdrivers and other accessories.

The design of the VAZ-2107 gearbox is a hypoid gear with offset axes. This structure reduces noise levels during grinding of mechanism parts. But at the same time, additional sliding can cause knots to jam. High-quality lubrication protects against the occurrence of this type of malfunction.
Design and technical characteristics of the gearbox
The rear gearbox of the VAZ 2107 car consists of a massive steel casing with a shank, a driveshaft flange, two main gears mounted at right angles to each other and a self-locking differential.
The main elements of the gearbox are the housing, the main pair of gears and the differential with satellites
Rear gear ratio
The main characteristic of any gear transmission is its gear ratio. It is the ratio of the number of teeth on the driven gear to the number of teeth on the drive gear. The driven gear of the VAZ 2107 rear gearbox has 43 teeth. And the drive gear has 11 teeth. Dividing 43 by 11 we get 3.9. This is the gear ratio on the VAZ 2107 gearbox.
Another important point should be noted here. VAZ 2107 was produced for many years. And over the years, gearboxes with different gear ratios were installed on it. For example, the earliest models of the “seven” were equipped with gearboxes from the VAZ 2103, the gear ratio of which was 4.1, that is, the tooth ratio was 41/10. On later “sevens” the gear ratio changed again and was already 4.3 (43/10) and only in the newest “sevens” this number is 3.9. Due to the above reasons, the driver often has to independently determine the gear ratio of his car. Here's how it's done:
- the car is set to neutral gear;
- The rear of the car is raised using two jacks. One of the rear wheels is securely fixed;
- After this, the driver manually begins to turn the driveshaft of the car. It is necessary to make 10 revolutions;
- By rotating the driveshaft, you need to calculate how many revolutions the unfixed rear wheel will make. The number of wheel revolutions should be divided by 10. The resulting number is the gear ratio of the rear gearbox.
Bearings
The rotation of all gears of the gearbox is ensured by bearings. In the rear gearboxes of the VAZ 2107, single-row roller bearings are used on the differential, and the rollers there have a conical shape. Bearing marking is 7707, catalog number is 45–22408936. The price of a bearing on the market today starts from 700 rubles.
All rear gear bearings of the “seven” are roller, single-row, tapered
Another bearing is installed in the gearbox shank (i.e., in the part that connects to the cardan). This is also a tapered roller bearing marked 7805 and catalog number 6–78117U. Standard VAZ shank bearings today cost from 600 rubles and more.
Planetary pair
The main purpose of the planetary pair in the rear gearbox of the VAZ 2107 is to reduce engine speed. The pair reduces the crankshaft speed by about 4 times, that is, if the engine crankshaft rotates at a speed of 8 thousand rpm, then the rear wheels will rotate at a speed of 2 thousand rpm. The gears in the planetary pair of the VAZ 2107 are helical. This solution was not chosen by chance: a helical gear is almost twice as quiet as a spur gear.
The planetary pair has a helical gear to reduce noise levels
But helical planetary pairs also have a disadvantage: the gears can move along their axes as they wear out. However, this problem is relevant for racing cars, the rear axles of which have exclusively spur gears. And for all the years of production of this car, the VAZ 2107 had exclusively helical planetary pairs.
When replacement may be needed
The lubricant loses its properties over time. The oil be changed regularly, according to the instructions. But during operation, signs of malfunctions may appear, which indicate the need for a faster change of waste fluid:
- whistling and noise appear from the side of the bridge;
- when the nature of the load changes, knocking noises become audible;
- There are drips and traces of oil fluid on the gearbox.
The car care instructions state that in the VAZ-2107 the rear axle oil is changed for the first time after running in (2000 km). And then it needs to be changed every 60 thousand kilometers. But, given the difficult climatic conditions with ultra-low temperatures, bad roads and constant driving in city traffic jams, it is recommended to fill in new oil after 30 - 35 thousand kilometers. Unscheduled maintenance when purchasing a used car, major repairs are also accompanied by the replacement of lubricant.
Experts advise changing the lubricant in different seasons (winter and summer). In winter, the oil composition should be more liquid, with a lower pour point. And in summer it is more viscous.
Why do you change the oil?
The rear axle gearbox is a mechanism that is subjected to a number of different loads. Through these loads, destructive actions occur. To avoid accelerated wear of gearbox parts, it is necessary to use a special lubricant. This lubricant is an oil that, during the operation of the gears of the mechanism, envelops them, eliminating accelerated wear and overheating, and also cleans the teeth from chips and metal dust.
It is necessary to change the oil in the rear axle gearbox for the simple reason that over time it loses its primary properties. When the gears rub against each other, thermal energy is released, the value of which is reduced with the help of a lubricating fluid. In addition, when the gears rub, the teeth wear out, resulting in the formation of chips and metal dust. If you do not change the lubricant in the gearbox for a long time, the amount of metal shavings and dust will only increase, which will lead to accelerated wear of the rubbing parts.
How much oil is required
Before proceeding directly to the procedure, you should decide how much oil to fill. According to the manual, the volume of oil required in the drive axle gearbox of the “classic” is 1.35 liters. Therefore, when preparing for the procedure for changing it, it is recommended to prepare a larger amount - approximately 1.5 liters of liquid. The remaining volume is needed for internal cleaning of the gearbox: the mixture with diesel fuel is poured.
Second phase
The gearbox is flushed during the fluid replacement process. To flush the rear axle gearbox, you need to mix transmission or engine oil with diesel fuel. The proportion should correspond to 3: 1. Washing consists of the following sequence of actions:
- Draining old grease;
- Cleaning the system from dirt, sediment and mixture residues;
- Wiping all containers and cases;
- The prepared mixture is poured into the system;
- Next, you should jack up one wheel, start the engine, switching to first gear;
- Wait a few minutes;
- Drain the flush.
The gearbox is flushed once every 4–6 months, when undergoing scheduled repairs or replacing transmission fluid.
First stage
Having installed the car on the inspection hole, you can begin draining the old oil from the gearbox on the VAZ 2107. The procedure is carried out in the following sequence:
- Remove dirt from the drain and filler plugs;
- Place a container for draining under the drain plug;
- Unscrew the drain plug with a 12 key;
- Carefully drain the old oil;
- Tighten the drain plug.
Draining the oil is done with the engine warm; work must be done with caution to avoid burns. The liquid must drain completely, since heavy suspensions are always found in the thickness of the sediment, which drains last.
Replacing oil seals
If an oil leak is detected in the machine components, it is necessary to replace the VAZ 2107 gearbox seals.
Replacing the cuff of the drive gear of the rear axle gearbox of a VAZ 2107
Rear axle malfunctions due to oil leakage:
To replace the VAZ 2107 gearbox seal on its drive gear you will need:
- Wrenches for “13” and “24”.
- Screwdrivers.
- Calipers.
- Torque wrench.
- Dynamometer.
- Mounting blade.
- Durable cord.
Instructions for removing the cuff
So:
Replacing the oil seal in a VAZ 2107 gearbox begins with draining the oil from the crankcase mounted on the rear axle. After this, the plug on the oil drain hole is screwed back on. Both axle shafts are removed from the beam on the rear axle. The four nuts are unscrewed and the bolts connecting the universal joint flange and the drive gear flange are removed. To fix the cardan (see) from turning, it must be held with a mounting blade. The flanges are separated using a screwdriver. A strong cord is wound around the drive gear flange. To do this, you need to make several revolutions of the shaft. Then, while winding the cord using a dynamometer, check the moment of resistance when turning the drive gear. Its meaning is remembered
This is very important when replacing the rear axle gearbox seal on a VAZ 2107. Unscrew the nut holding the drive gear flange, which is fixed with a special key, and remove the flat washer.
- The flange is removed.
- The drive gear oil seal is removed from the crankcase neck of the assembly, for which it is pryed off with a screwdriver.
Installing a new oil seal
So:
- The seat is cleaned of traces of corrosion.
- Litol-24 lubricant is used to lubricate the working surfaces of the crankcase of the new cuff.
- The oil seal is put in place and pressed into the gear housing through a mandrel with light blows of a hammer. The oil seal must not be skewed. The pressing depth is 1.7 - 2 millimeters from the end of the crankcase.
- After the oil seal on the VAZ 2107 gearbox has been replaced, the drive gear flange and washer are installed.
- The flange is held with a special wrench and the nut securing it is tightened. The tightening torque depends on the moment of resistance of the drive gear to turning, and is equal to 117 - 254 Nm.
It is necessary to start tightening with a smaller torque, periodically checking the resistance moment of the nut being tightened.
Once the VAZ 2107 axle gearbox seal has been replaced, installation of the removed parts is done in the reverse order of removal.
In this way, the rear axle gearbox seal of the VAZ 2107 is replaced.
Changing the oil in the steering wheel of a VAZ yourself
The oil change in the steering wheel of a VAZ is carried out after tens of thousands of kilometers. During operation, you need to monitor the oil level in the gearbox. Lack of control and untimely oil change in the steering mechanism of a VAZ can lead to unpleasant consequences, accompanied by difficulty in rotating the steering wheel, a decrease in the quality of vehicle control and an increase in play.
Work order
Unscrewing the plug for filling oil into gearbox of a VAZ 2107
- Place a container under the drain hole to collect used oil.
- Use a hex wrench to “12” to unscrew the drain plug to remove the used oil.
- After the liquid has completely drained, the drain plug is screwed into place.
Advice: If the oil drained from the gearbox housing has a dark color or metal particles, the rear axle gearbox must be washed.
- To flush, you need to fill in about one liter of a mixture of thirty percent kerosene with gear oil. Instead of kerosene, you can use diesel fuel.
- One rear wheel is lifted, first gear is engaged and the engine is started.
- After three minutes, the washing mixture is drained.
- For filling, it is better to use an oil blower or a lever grease gun. If you don’t have them on hand, you can use a large plastic syringe with an elastic tube attached to its end.
- 1.3 liters of special transmission oil is poured into the gearbox.
- It is necessary to ensure that its level reaches the lower edge of the filler hole.
After filling the oil, the breather is checked and cleaned of dirt. This device is necessary in order to relieve excess pressure in the gearbox that is formed when the oil heats up and when its level rises. All operations for changing the oil on a VAZ 2107 car can be clearly seen in the video.

Under what conditions is replacement made?
It is recommended to simultaneously replace lubricants in two automotive components:
- checkpoint;
- gearbox (rear axle).
In addition to the above cases, replacement of the transmission substance is necessary when:
- the fluid level drops below the recommended level;
- the presence of silvery dust in the transmission substance;
- change in the color of the fluid (black color or a brown-coffee tint indicates the destruction of additives or water entering the gearbox).
We can safely say: the quality of the transmission oil determines the condition of the gearbox or even the entire car. Therefore, it is quite acceptable to change the fluid more often. For example, after 20–25 thousand. km run.
Oil for the rear axle gearbox of the VAZ 2107: selection, replacement
The domestic car VAZ 2107 is a rear-wheel drive vehicle. The rear wheels are driven by the rear axle and cardan drive. An important role in this is played by the rear axle, which is a gearbox for converting torque from one value to another. This is the mechanism in which the gears rotate. Oil is used to reduce friction on these gears. What kind of oil is recommended to be poured into gearbox of the VAZ 2107 will be discussed in this material.

Some of the main factors that influence the timing of oil changes are:
- Driving character. Frequent and abrupt starts are not at all beneficial to the parts and mechanisms of the car, including the rear axle.
- Vehicle operating conditions. If the car is used in rural areas where there are poorly paved roads, dust, and dirt, then replacement should be done more often.
- Lubrication quality. It is recommended to fill the rear axle of the VAZ 2107 with special high-quality oil. If you pour low-quality lubricants into the gearbox , you will need to replace them much more often.
- Operating a vehicle with a trailer. The wear of the device parts will accelerate if the car is operated with a trailer in which cargo is transported.
VAZ 2104: oil change - tips from experienced
Change the oil? No problem!
Are you the owner of a beautiful VAZ 2104 car? Then you've come to the right place. It's time to change the oil of your beloved iron horse. Or it didn’t arrive - how do you know? What kind of oil should I fill in? In what quantity? The answers to these and other questions are provided by these detailed instructions for changing the oil yourself. This article describes how to properly change the oil in the main components of a VAZ 2104 car (where oil is required). Photos and videos are also provided to help you.
The process of changing the oil in the gearbox
Changing the oil in the gearbox is carried out simultaneously with replacing the transmission. Three main reasons that indicate a fluid change in the gearbox:
- Corrosion of metal;
- The wear of gear teeth increases;
- Accumulation of wear products in the lubricant.
In addition to the main factors requiring replacement of the mixture, there are additional reasons. When buying a car secondhand, it is not known what kind of fluid was used to lubricate the gearbox system. There is also no exact data on when the mixture was replaced. The risk of exceeding the frequency of lubricant changes can lead to serious consequences.
The frequency of changing the lubricant in the gearbox is always in the vehicle operating instructions. In the absence of these recommendations, for cars with a manual transmission, the change interval is 50-60 thousand kilometers; with an automatic transmission, the mileage is two times less - 25-30 thousand kilometers.
The timing of lubricant changes also depends on the operating conditions of the vehicle. If driving conditions are difficult, change the oil more often. Changing the oil in the VAZ 2107 steering gear is carried out in compliance with safety regulations.
Work is carried out in a viewing hole or overpass, away from children, wearing special clothing and rubber gloves. Before you start changing the fluid, the power unit must be warmed up, this will increase the fluidity of the lubricant and make it much easier to drain.
List of necessary tools for changing fluid:
- Set of wrenches;
- Hexagon 12;
- Latex gloves;
- Rag;
- Container for draining used lubricant;
- New oil ;
- Syringe or hose.
Having prepared everything necessary for changing the oil and warming up the power unit, you can begin the main process.
Changing the oil in the rear gearbox of a VAZ 2107
Preparation for replacement and necessary tools
So, changing the oil in the rear axle of a VAZ 2105 or another car is most conveniently done in a pit or overpass. Think in advance where you can find them. Buy oil for filling - you should take 2 liters - there will be a little left for topping up.
Advice! Before changing the oil, be sure to warm up the car by driving it for about 10 kilometers. This way the oil will drain better.
What tool will you need:
- Hexagon 12
- Socket wrench or 17mm socket with wrench
- Oil syringe
- Containers for waste oil
- Rag
- Rubber gloves to prevent oil from burning your hands
As you can see, changing the oil in the axle of a VAZ 2104 and other cars does not require any special costs and can be done with your own hands.
How to change the oil in the steering gearbox, also known as the steering mechanism, on a VAZ 2101-VAZ 2107?
Note! Before you start replacing, check the oil level in the system and be sure to look where the steering mechanism is located and how to understand when it’s time to change the oil! (For answers to all these questions, see the article: “Checking the oil level in the steering column”)
Draining: 1) First, check that the car’s engine is warmed up to operating temperature, and if necessary, then get into the car and warm it up so that the engine is warmed up to its operating temperature.
Note! This is necessary so that the old oil drains faster from the steering gear housing, and also so that dirty oil residues also come off the cylinder walls. Also, keep in mind that when the engine is warm, the oil will be hot, so be careful and don’t hurt your hands!
2) Now completely unscrew the upper bolt of the oil filler neck, and into the hole that will appear after the bolt is unscrewed, you will need to insert a syringe specially designed for filling oil and with its power, collect all the oil that will be inside the gearbox, as shown in the small photo.
3) When the oil is collected using a syringe and poured into a container, check its condition. Foreign bodies such as small metal particles, etc. should not be found in the oil, so if unwanted parts are noticed, then you will need to rinse the gearbox from them, but it is not so easy to rinse the gearbox, firstly you will need a special a supercharger with a dispenser (working on the principle of excess pressure) with the help of which it will be possible to direct the oil in the gearbox from bottom to top, but this supercharger is mainly available only in car service centers, therefore we recommend that you wash the gearbox there.
Note! It is recommended that it is best to fill the steering mechanism with TAD 17 transmission oil, but if the car is operated at sub-zero temperatures, then you will have to refuse to fill such oil, because it freezes at sub-zero temperatures!
Filling: Filling the oil back is very simple, through the filler hole using the same syringe new oil is poured into the gearbox housing, that’s basically all, and when the oil is filled in, tighten the top filler plug and you can assume that you have oil changed.
Note! Before tightening the oil filler plug, wipe it completely free of dirt with a clean rag!
Additional video: There is an interesting way by which you can change the oil in the steering gear, it is described in the video located just below, check it out and decide whether you need to change the oil in the steering gear or not.

Changing the oil - VAZ 2104
Before repair work, you should prepare a little:
- Warm up the car - for the engine: start it and let it run for 10 minutes to warm up the oil. For the gearbox and rear axle, you should drive the car for about 10 kilometers. Then the oil will drain better and there will be fewer impurities in the new one.
- Purchase the required amount of oil and an oil filter. You will need one canister of engine oil (5 liters - the rest will be left for topping up), and 3 liters of transmission oil (again, it is better to take it with a reserve so as not to run to the store twice).
- Find a suitable location for renovation work. An inspection hole is an ideal option. It can be replaced with an overpass.
Changing the oil on a VAZ 21043 is best done in a pit in the garage
Advice! Do not change the oil in the open air while you are under the car. You may end up in oil, and the presence of wind will in no way help speed up the process.
Now that everything is ready, you can change the oil. Begin.
Changing the engine oil
- The factory engine protection is designed so that there is access to the oil drain hole. But homemade protections are often installed that completely cover this hole. In this case, you will need to remove the protection.
- For the next step you will need a 12mm hexagon. Use it to unscrew the drain plug located in the engine oil pan.
- Place the waste container under the stream of oil.
- Wait about 10 minutes until the hot oil drains from the pan into the container.
- Then you can screw the plug back on.
Advice! Wipe the area around the drain plug with a rag. This is done to better control leakage after an oil change.
- Now you can flush the engine. This is done in accordance with the instructions for the flushing oil.
- Do not use five-minute washes because they do not flush the engine, they only thin the oil so that it drains better.
- After flushing the engine, you can begin replacing the filter and adding oil.
- The filter is removed with a puller (although this can often be done simply by hand). Using a puller, pinch the filter and tear it out of place. Then twist it by hand.
- Clean the seat under the oil filter from dirt and possible residues of the rubber filter seal using a knife or other sharp object.
- Screw the new filter into place BY HANDS, after pouring a little oil into it and lubricating the rubber seal with engine oil.
- Now that the filter is installed, you can fill in new oil.
- To do this, you need to unscrew the filler neck, which is located under the hood on the valve cover.
- Insert a watering can into the filler hole to prevent oil from getting onto the engine.
- Fill in the oil and monitor its level in the engine using the oil dipstick.
- The oil level should be between the minimum and maximum marks.
- After the required amount of oil has been poured into the engine, you can screw the filler plug back in.
- Pay attention to the condition of the plug. If it is loose or does not fit tightly in the hole, it is better to replace it.
Checking the condition of the lid
- After changing the oil, check the drain plug for leaks. Tighten it if necessary.
- Reinstall the engine protection.
- Start the car and let it run for about a minute.
- In the first 10 seconds the oil pressure indicator should go out.
- Then you should check the oil level again and add the required amount.
Changing the transmission oil
Advice! Before changing the oil in the gearbox, clean the gearbox body from dirt, especially the drain and filler plugs.
- Take a 12mm hexagon and unscrew the drain plug in the lower gearbox cover.
- Place the container and wait until the oil is completely drained from the gearbox.
- Then screw the drain plug back on.
- Now you will need a 17 key or socket. Unscrew the drain plug, which also serves as the oil level in the gearbox.
- Using a syringe, you need to pour oil into the gearbox housing. A syringe can be used either special or homemade, and a watering can with a hose can also be used.
- A sufficient amount of oil has been filled - this is when it starts to drip from the filler hole.
- Quickly screw back the filler plug to avoid contaminating the surrounding work area.
- Wipe the box body with a rag to check for leaks.
- Check for leaks from under the plugs and bottom cover. Tighten if necessary.
- Clean the breather using a thin wire or needle.
