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.

How to change the oil on the rear axle of a VAZ 2107

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.

When replacement may be needed

The lubricant loses its properties over time. The oil in the bridge must 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.

The oil on the rear axle of the VAZ-2107 needs to be changed every 30 km

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.

Oil for gearbox, transfer case and axles of VAZ-2107

VAZ-2107 is a rear-wheel drive small class sedan, 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 sedan, the updated line consisted of the 2104 station wagon and the 2105 sedan, 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 by the Lada Granta in 2012.

Checking the oil level

Control checks of the fluid volume in the gearbox should be carried out every 10 thousand kilometers, as well as when malfunctions or visual leaks occur. Checking the oil level in the rear axle is quite simple. To do this, you will need a container with a volume of about one and a half liters, a 17mm wrench and a screwdriver. The next steps are:

the car is placed on a viewing hole, overpass or lift;
the filler plug is cleaned of dirt;
use a 17 key to unscrew the filler plug;
The oil level is controlled with a screwdriver: the liquid should reach the edge of the hole.

If there is insufficient protective liquid, it is necessary to add it using a syringe or other device.

Capacity for filling oil into the rear axle gearbox of VAZ 2107

You won’t believe it, but there are also owners who don’t even know that the rear axle of a car also needs regular lubrication, although not as often as the engine. Also, there are drivers who believe that if the oil does not expel or ooze, there is no need to change it at all. This is all wrong and it is also necessary to perform this procedure, as in the internal combustion engine and in the gearbox.

The lubricant volume should be 1.3 liters. To fill the required level, you need to wait until the oil flows from the filler hole; this will be considered the optimal volume.

Which lubricant to choose

Many drivers have a reasonable question: what oil to fill? Mechanics recommend pouring oil into the rear axle gearbox of a VAZ-2107 with a viscosity of 75W90, 80W90 or another suitable one with API classification GL-4/GL-5. For example, Castrol 75W90, Lukoil 80W90. In winter, it is better to fill the rear axle of the VAZ-2107 with synthetics. In summer, mineral water.

How much oil to pour into the engine, gearbox and axle of a VAZ 2107

Many VAZ 2107 car owners are interested in the question: how much oil should be poured into the main components of the car, such as the engine, gearbox or rear axle? In fact, this information is included in every vehicle operating manual that is issued upon purchase at a car dealership. But if you are the owner of a used vehicle or for some other reason do not know what the main filling capacities of important units are, then this information will be provided in more detail below.

Oil change instructions

You can replace the gearbox lubricant in an inspection pit, overpass or lift. Before driving the car into the pit, you should drive a little and warm up the axle fluid. You should also prepare in advance a tool (a set of keys and screwdrivers), containers for working, protective gloves, rags, a special syringe or a device with a hose for pouring.

The old oil is poured into a pre-prepared container

Changing the oil in the rear axle gearbox of the VAZ-2107 is performed in the following order:

Clean the drain and filler plugs from any dirt.
Using a 12mm wrench, unscrew the drain plug.
Drain the old gear oil into the prepared container. Remember that the liquid will be hot after warming up.
Tighten the drain plug.
Unscrew the filler plug.
Pour in enough oil to reach the bottom edge of the hole.
Tighten the filler plug. Make sure there are no leaks.

If inspection of the used fluid shows severe contamination, then you need to rinse the gearbox before filling in a new one. To do this, mix transmission or motor oil with diesel fuel in a ratio of three to one. The resulting mixture is poured into the reducer. One wheel is lifted with a jack. The engine starts and first gear is engaged. This process takes several minutes. After this, the cleaning fluid can be drained and new drive axle grease can be added.

How many liters of oil are in the axle gearbox of a VAZ 2107

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.

How much to fill (volume)

You won’t believe it, but there are also owners who don’t even know that the rear axle of a car also needs regular lubrication, although not as often as the engine. Also, there are drivers who believe that if the oil does not expel or ooze, there is no need to change it at all. This is all wrong and it is also necessary to perform this procedure, as in the internal combustion engine and in the gearbox.

The lubricant volume should be 1.3 liters. To fill the required level, you need to wait until the oil flows from the filler hole; this will be considered the optimal volume.

Replacement

The oil is changed according to the same algorithm as the oil in the gearbox, after a mileage, so that the oil is hot and drains better:

- unscrew the filler plug

— place a container for used oil under the drain hole

- unscrew the drain plug

- after the oil has completely drained, tighten the drain plug

- pour oil into the filler hole until oil flows out of it

- tighten the filler plug

Which one to pour?

It is recommended to fill the VAZ 2107 rear axle gearbox with transmission oil with a viscosity grade of 75W90 or 80W90 with API specification GL-4/GL-5. For example, CASTROL Syntrans Transaxle 75W-90 API GL-4 or Lukoil 80W90 GL-5.

In terms of volume, 1.5 liters of liquid is sufficient for replacement. Change at intervals of 30-40,000 km or every 3 years, whichever comes first.

We will talk about changing the transmission oil in the rear axle gearbox and gearbox (gearbox) on the Classic! In case someone forgot how to do this or still doesn’t know!))

It is recommended to change the transmission oil in the gearbox and rear axle reducer every 35,000 km or after three years of vehicle operation. It is also advisable to check the level and condition of the transmission oil immediately after purchasing a used car. The oil should be changed if: the oil in the gearbox housing and gearbox is below the recommended level, there is silvery dust in the oil (precisely dust, if you find metal particles in the oil, then it is most likely too late to change the oil and you need to prepare for serious repairs), The color of the oil is black or coffee (which may indicate the destruction of additives in the oil or water entering the oil). And, of course, you can change the oil in both the gearbox and the rear axle gearbox on your own! How to do this and what you will need for this, read on...

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.

Viscosity type

This parameter determines the operating temperature range supported by the oil. This parameter determines the temperature conditions under which the VAZ-2107 can be operated. So, let's consider suitable viscosity parameters for the VAZ-2107:

SAE75W90. This parameter marks synthetic and semi-synthetic oils intended for operation of the VAZ-2107 in any weather. This lubricant is suitable for regions with constantly changing climates. Temperature range – from -(minus) 40 to +35 degrees.
.SAE75W85 - this lubricant is also suitable for all-season use, but it also has a much larger range of supported temperatures - from - (minus) 40 to +45 degrees.
SAE80W85 is also a good option, but with a more limited temperature range - from - (minus) 30 to +35 degrees.

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).

What oil to use for gearboxes and axles

Original

Transmission oil on a mineral or semi-synthetic basis is poured into the rear axle gearbox of a VAZ-2107 car. For cars of recent years of production, semi-synthetic is recommended. As for viscosity, SAE 70W, 80W or 85W is suitable for winter use, and SAE 90, 140 or 250 is used mainly in summer. In Russian operating conditions, the most popular is multi-grade oil with SAE 75W-80, 80W-85, 80W-90 or 75W-90.

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.
