Replacement and selection of rear wheel bearing Lada Granta

When a wheel (wheel) bearing breaks, it must be replaced. This detail, small in size, is very important; it ensures freedom of rotation of the hub mechanisms. Continuing to use a broken one is dangerous: it will jam, and then a major accident cannot be avoided. The range offered at car markets is quite wide. To decide which wheel bearing is better, it is useful to study its characteristics and the features of bearings offered by different companies. Of course, your choice will be influenced by what exactly you want: to qualitatively repair your favorite car, sparing no expense, or simply to make inexpensive repairs and put the car up for sale.

The wheel bearing is one of the most heavily loaded suspension elements. Wheel bearings allow wheels to rotate and the vehicle to move as a whole. In addition to the perception of loads directly from the wheel rolling on the road, shock and thermal loads are added. Through the hub bearing, all forces arising in the contact patch between the wheel and the road are transmitted to the suspension.

That is, of the suspension and the car depends on the correct choice of front and rear wheel bearings . The main problem when replacing wheel bearings is the large number of low-quality fakes on the market that last no more than 2-3 thousand km, as well as violation of installation technology and incorrect adjustment of clearances.

Malfunctions of wheel bearings manifest themselves in the form of hum, knocking and play when the car is moving, clicks when starting and stopping. As raceways, rolling elements and cages wear, rolling resistance increases and this is accompanied by increased noise and heating of the bearings.

You can determine the malfunction of the wheel bearings yourself. To do this you need:

1. Check ease of rotation. Spin the suspended wheel with a sharp jerk and evaluate the noise level emitted by the bearing during rotation. The wheel run-out time is also estimated.
2. Determine the presence of play in the hub bearing. On a suspended wheel, applying a load with your hands in the vertical and horizontal planes, check for swing (play) in the bearing. By applying force along the axis of rotation of the wheel, you can estimate the axial clearance.

SS20 wheel bearings will help you avoid problems with low-quality spare parts. The reliability and durability of SS20 bearings is achieved through:

• accuracy of geometric dimensions in the design and production of a product;
• use of high quality steel;
• achieving the required level of surface roughness;
• use of high-tech equipment.

The manufacturing precision of wheel bearings, surface roughness and rolling elements are the key aspects that influence the level of mechanical losses in the bearing and, ultimately, determine the noise class.

During production, the service life of the hub bearings is checked selectively from the batch before failure on a stand that simulates real loads on the bearing. As part of a comprehensive quality assessment, bearing runout is checked with an assessment of the reduction in speed at two stages from 100% to 70%, and the drop in speed from the initial stage to a complete stop. At the same time, the vibroacoustic parameters of the freewheel bearing are checked.

A whole range of serious checks at all stages of the production process allows us to guarantee the buyer the high quality and reliability of SS20 wheel bearings.

SS20 hub bearings have the SS20 branding and additional protection against counterfeiting, which will provide car owners with confidence and safety on the road, and protect them from possible financial and time losses when using counterfeits.

Front wheel bearings for VAZ 2101-07 and 2121, 2123 are supplied as part of repair kits. The SS20 front hub repair kit contains all the washers, oil seals, rings, nuts, bearings and special high-temperature complex lithium grease for bearings required for replacement.

The high quality of the lubricant ensures a service life of up to 300,000 km in the wheel bearing assembly. The amount of grease is calculated to ensure reliable lubrication of the bearings throughout their entire service life. The operating temperature range of the lubricant is from –40°С to +180°С.

We draw your attention to the process of adjusting the clearance in the hub bearings. The durability of the unit largely depends on the correctness and quality of this operation, therefore, we offer you step-by-step instructions (included in the delivery kit) that will allow you to adjust the clearance in the wheel bearing unit, both during initial installation and during further scheduled maintenance.

Repair kits for front and rear hubs of front-wheel drive VAZ cars

In the hub units of front-wheel drive VAZ cars, double-row ball bearings are used. During assembly, the required amount of lubricant is placed in the bearing. The internal space of the bearing is reliably sealed with oil seals, which prevents contamination from getting inside. This ensures normal lubrication of the raceways, balls and cages throughout their service life. Wheel bearings SS20 for front-wheel drive VAZ cars are maintenance-free and do not require adjustment or lubrication during operation. This approach significantly reduces the labor intensity of vehicle maintenance and at the same time ensures high reliability.

The reliability of the bearing directly depends on the accuracy of manufacturing and compliance with all standards during the production of the bearing. Therefore, for SS20 double-row ball bearings we carry out a number of additional checks, for example, monitoring the amount of axial clearance and radial “runout” in the mounted state.

List of companies

Well, now we come to the most interesting part.
Now I want to introduce several serious manufacturers that you can choose from. I want to say right away that I will not take Chinese and Russian brands, we will take a walk through the famous ones. 1) SNR is a large French company, widely represented in Europe, less so in Russia, but quality is practically in first place.

2) SKF is the world's largest company, ranks with SNR, and is widely represented in Russia. Very high quality manufacturer.

3) FAG is a leading manufacturer in Germany, not as large as the first two, but the quality is at the same level. Recently acquired by INA

4) NSK is the second wheel bearing manufacturer in the world after SKF. The headquarters is in Japan.

5) NTN - Japanese domestic manufacturer, rarely represented in Russia.

6) Koyo - part of the TOYOTA company, the third largest in Japan.

7) Timken is the first American manufacturer of bearings.

INA is a very large concern, but it produces bearings for engines, transmissions and timing belts; it recently absorbed FAG, and therefore is beginning to enter the “hub” business under its own brand.

I would like to note that some of these manufacturers work only for brands (conveyor) and practically do not work for the spare parts market.

What are the signs of bad wheel bearings?

Signs of bad wheel bearings include the following:

• A rumble or hum that gets louder when accelerating or turning.
• Constant loud howling or squeaking sound when the car is moving
• Clunking sounds when driving on uneven surfaces

2. Excessive play or free movement of the steering wheel (uninformative steering wheel); 3. Vibration of the steering wheel, changing depending on the speed of the car or when turning; 4. ABS malfunction. Problems with the ABS system may be due to a faulty ABS sensor integrated into the wheel bearing.

What are the dangers of driving with a bad wheel bearing?

It is extremely rare for a wheel bearing to fail immediately and completely after you notice the first signs.

However, it is best to avoid long trips with a worn wheel bearing. As we already know, the wheel bearing is extremely important - it connects the wheel to the car. Any problem in this connection can have very serious consequences for the drive axle and steering system, as well as for your safety.

Replacing wheel bearings

Although today's wheel bearings are easier to install than in the past, correct installation, using the correct tools, and maintaining the specified torque values ​​are still important for maximum performance, longevity and safety. Therefore, we recommend that wheel bearings be installed by a professional mechanic with the appropriate skills and tools.

Replacing the Grant rear wheel bearing

To find out what condition the Lada Granta rear wheel bearing is in, you need to hang the wheel in a free state and rotate it by hand. Ideally, the wheel should spin evenly and smoothly without knocking or sticking.

Replacement with the rack not removed

Design and operation Wheel bearing. What are bearings for?

This method will allow you to avoid subsequent collapse. Here you need to remove:

• wheel together with disk;
• caliper and the hub itself.

Replacement is carried out directly on the car, without removing the rack. Here you will have to work with a puller. The procedure is performed like this:

• unscrew the bolts from the brake drum and remove it;
• remove the ball joints;
• pull out the CV joint from the front hub, and then remove it itself using a chisel;
• the retaining ring is pulled out from the steering knuckle (it contains the outer part of the damaged bearing);
• the puller is installed directly on the fist;
• by tightening the bolt of the device, the part is pressed out;

When it completely leaves the axle, the protection is dismantled, then the hub is removed, from which the inner race is removed.

You can also remove the latter without a puller, but you will need a chisel for this. It’s also quite easy to score with a grinder and then split with a heavy hammer.

Which bearing manufacturers can you trust?

It doesn’t matter whether you need to buy a rear or front wheel bearing, you should pay attention to products only from trusted manufacturers. Therefore, we recommend products from reputable manufacturers such as SNR, NSK and Iljin. These manufacturers care about the quality of materials, assembly and lubrication of bearings. Several years may pass before the first signs of wear appear; the car will travel several hundred thousand kilometers. At the same time, the price of these bearings is not bad and is completely justified. * Please check the applicability of parts specifically for your car with our managers by phone (calls within Russia are free).

Useful tips

By following these guidelines you will ensure that your new bearings last longer:

• when replacing a damaged part, place a new one on both front wheels, so the entire system will work more stable (after the procedure, the wheel alignment is checked);
• the bearing is cooled before use, and the rotating mechanism, on the contrary, is heated, this will allow pressing to be carried out with minimal labor costs;
• try to buy new spare parts in stores with a good reputation that have the necessary certificates of conformity and other documents confirming the quality of the products sold.

Measure Before Buying

What to look for at first glance

1) First you need to understand whether your car comes with or without ABS. After all, the differences here are truly striking. A car with ABS has a bearing with a magnetic washer, but a car without such a washer does not. Previously, one manufacturer could find different configurations of machines.

2) On the edge, either in the upper part or in the lower part, there must be an engraving of the manufacturer, as well as the country of origin; there may also be digital indicators (sizes, for example). If there is no country of origin, DO NOT TAKE IT, most likely it is a fake.

3) The bearing must be supplied with a hub nut; as a rule, it is disposable; on some models, studs (if provided), bolts or pins, and sometimes seals.

Grant ball joint which is better

Selecting quality parts for car maintenance and repair is an important task for every motorist. In order for the car restoration to be high-quality and durable, it is better to use the most interesting options for parts with a sufficiently high quality. It is worth remembering that the reliability of spare parts determines their service life, as well as the quality of operation. Unfortunately, the cost of parts also greatly depends on this factor. Today we will talk about the racks that are best used on the Lada Grant. Considering the fact that factory suspension elements fail after a maximum of 50,000 kilometers, you have to look for something more interesting and non-standard. You can buy factory solutions again only under warranty, when you will receive a free replacement and will not charge money directly for the racks.

Today you can buy a shock absorber liner from any manufacturer, including some of the most amazing brands from around the world. In this case, it is not necessary to change the rack assembly; you can make a constructor by installing an insert of a specific selected type. This will completely change the behavior of the car. The stock shock absorbers on the Grant are simply amazing - they behave exactly as the Lada 2110 did back in 1998. There have been no significant changes in the suspension. At least regarding the struts and operating comfort of the car. There are different brands and specific recommendations for the types of racks. Let's take a closer look at each aspect of purchasing new suspension parts. This will help you better service your car and obtain the necessary features for operating a vehicle.

Oil or gas-oil - the first question that needs to be resolved

If you take inexpensive racks that are made in Russia or China, then there are virtually no differences between oil and gas-oil. But when you buy products from a great brand, you can notice a very noticeable difference. In particular, gas-oil will be a very tough sports solution. Oil shock absorbers offer customers a number of specific advantages that will be important in the operation of vehicles:

• quite high ride comfort, which can be called significant progress for the Lada Granta, overcoming most potholes without noticeable effects in the car interior;
• low level of penetration, that is, you will not catch unpleasant sounds when the rack shows its long free stroke, there is no risk of breakage;
• the rod stroke is quite long, it is possible to hang the wheels almost like an SUV, this helps on large bumps and dirt roads;

Of course, it all depends on the brand. You can buy an excellent Japanese version of the insert and get simply wonderful operating possibilities. There is the option of purchasing a cheap Chinese rack and being completely disappointed in its use. But for now, let's limit ourselves to making a decision on the type of shock absorber. It can be a soft oil or a sports gas-oil type.

Manufacturer is one of the most difficult questions for the buyer

Buying unusual, expensive shock absorbers is becoming a necessity today. In conditions of very tough competition and the global crisis in the automotive market, cheap companies are starting to produce worse and worse spare parts. Therefore, the products of some corporations have long ceased to be reliable and of high quality. It is worth highlighting the following brands as an ideal solution for Lada Granta when purchasing racks:

• KYB - you can combine separate liners with a stock strut and you will get an almost full-fledged Kayaba, the shock absorbers are very durable and high quality;
• Acomi is a fairly affordable brand, but much better than Chinese solutions, a completely acceptable solution if you choose an expensive series like Comfort PRO;
• SS20 - the company makes special racks for the Granta, so they fit perfectly, quite adequate quality, but there are many fakes and a number of shortcomings in movement;
• Demfi - not so durable, but quite affordable racks, which are also ideal for the Lada Granta, quite high-quality performance, but you need a choice;
• Plaza is one of the cheapest options of more or less decent quality, but only some kits from the manufacturer are pleased with their reliability and durability.

So there are not many chances to choose from brands. Of course, you can try Monroe struts or buy some racing solutions from France and Germany. But this will be too expensive. The same as Kayaba, but this solution is classic, and is simply perfect for the Lada Granta. If you have enough money for a Japanese manufacturer, buy their offers for your car.

Springs and strut supports for Lada Granta - choose the best

It is better to install original springs. No manufacturer offers the same accuracy as VAZ in this case. There is only one reason for this - no one wants a manufacturer of springs specifically for Grants to do it efficiently and cheaply. Therefore, you have to give preference to stock solutions. As for the upper and ball joints of the Lada Granta struts, it is worth paying attention to the following features:

• the upper supports of the front struts are most often installed in Russian SS20, there are options for using more expensive solutions, but this purchase takes a long time;
• but the rear upper supports for shock absorbers are not easy to find, the Acomi company will help you here, but it is better to contact the officials and buy what was originally in your car;
• VAZ ball joints are no good and cost 20-30 thousand, so it’s better to buy Belmag or Forward, which are made in Russia and cost very affordable money;

There is an opinion that factory spare parts are always better than analog ones. But in the case of the Lada Granta this is not at all the case. Sometimes you can find quite adequate spare parts that fit Granta from German and Japanese brands. And then you can buy really wonderful additions and parts that last for years. However, any part has its own service life, and this also needs to be remembered.

Replacing Lada Granta struts and supports - several important features

If the rear suspension is more or less clear, then the front suspension always hides more mysteries. It is the front struts and supports that most often fail. Unless you constantly pull a trailer or tow careless friends. The load on the front of the car is always increased, so you often have to work with the front suspension parts. Changing the front struts on a Grant is not so easy:

• first you need to completely remove the rack and disassemble the lower parts of the chassis for subsequent installation on a new mechanism for damping road irregularities;
• if the rack is installed as a new assembly, then there will be much fewer problems, you just need to install a new one in place of the old mechanism and reassemble it in the reverse order;
• if only the liner is changed, it is worth completely disassembling the strut, removing the spring and taking out the shock absorber, checking the degree of wear of all parts and the need to replace them;
• Next, you should replace the strut liner, carry out technical checks right at the assembly site and reassemble the shock absorber to its original position;
• Next will be the installation of the rack in place, assembly and rough diagnostics of all the components that you repaired, this will give complete confidence in the quality of the work.

You need to acquire tools such as a set of wrenches and sockets, a spring puller, a pry bar, pliers, screwdrivers and other available tools. Otherwise, you will not be able to completely disassemble the part and carry out its normal restoration. Of course, there are certain difficulties in carrying out this process, so it is better to take your Lada Granta for service and complete all the work in just over an hour. We invite you to watch the video of the process of replacing the strut on front-wheel drive VAZ vehicles:

Let's sum it up

There are a number of features of operating the Lada Granta on Russian roads. For some reason, a domestic car is not very suitable for our roads; it crashes and fails instantly. Sometimes you come across a well-built car that doesn’t show any character after 100,000 kilometers. But in most cases, the Garnet justifies the title of the cheapest car in the Lada line. And when it comes to racks, the manufacturer saves a lot on these elements. The installation of low-quality suspension elements leads to the fact that more and more people, after purchasing Grants, repair it under warranty.

However, sometimes it is better to cancel the warranty and install normal racks, supports and other parts. In this case, you will ensure the normal service of your car’s suspension and will be able to establish normal operation of each unit. This will take a certain budget, but can provide you with comfortable movement without any particular difficulties or problems. Of course, even the best quality rack will eventually fail. But it can travel far beyond 100 thousand kilometers. What brands of spare parts do you choose to repair the suspension of your Lada Granta?

Causes of drive failure

How to choose a vacuum cleaner for your car Cleaning the interior with an assistant

Replacing a vehicle's drivetrain is an infrequent occurrence, since the axle shafts are designed to withstand severe loads: factors such as gravity, tangential reaction associated with the start of the vehicle, lateral force, and even loads associated with strong crosswinds are taken into account.

Thus, the main reasons for failure and subsequent possible replacement of shafts are the following:

• an accident in which the wheel axle was thrown over an obstacle of appreciable height;
• daily long-term use of the car without proper attention paid to maintenance;
• leakage of the drive shaft boot.

Lubricant requirements for wheel bearings

High-quality lubricant for wheel bearings must meet a number of requirements:

• Do not spread at high temperatures: in summer, during the daytime, the asphalt warms up to +70 °C, and with increasing loads on the bearing assembly, the temperature can reach +140 °C or more
• Do not thicken or harden at subzero temperatures: otherwise the shear force will increase, the balls or rollers in the bearings will go into sliding friction, which will lead to increased wear and the formation of scuffing

Ideally, the lubricant should maintain its performance characteristics at temperatures from -40 °C (possibly lower) to +140 °C.

• Do not wash off with water that enters the unit from the road surface: washing out the lubricant threatens the spread of corrosion.
• Have optimal viscosity in order to maintain its structure under the influence of high speeds, temperatures and loads, ensure effective lubrication and heat removal.
• Be resistant to various chemicals (reagents, fuel, oil), neutral to rubbers and plastics - so as not to destroy oil seals and anthers

Currently, lithium and molybdenum greases are most often used for wheel bearings. Let's take a closer look at these groups.

Lithium greases

The most common and widely used not only for servicing wheel bearings, but also other vehicle components. Materials based on mineral, synthetic and semi-synthetic base oils thickened with lithium soap or lithium complex.

Lithium greases have a long service life and a fairly affordable price. They operate under loads of up to 2800 N, protect components from corrosion, are not washed out by water, and have fairly high anti-wear and extreme pressure properties.

Other properties of these lubricants depend on the characteristics of the base oil. For example, silicone lithium greases have a low coefficient of friction and high dielectric properties and are resistant to aggressive chemicals. Materials based on essential synthetic oils can withstand very high speeds (over 1,300,000 mm*rpm) and also have noise-reducing abilities.

Lubricants based on polyalphaolefin (PAO) oils have very low pour points, are characterized by low coking, high thermal stability, and oxidation resistance.

In complex lithium greases, the base oil is thickened with soaps of lithium salts of acetic, adipic, azelaic and other acids. They are characterized by a wider operating temperature range, greater resistance to water, high mechanical stability and reduced oil separation.

Molybdenum lubricants

Lubricants with molybdenum disulfide (MoS2) as an anti-friction additive.
Just like lithium, they can be mineral, synthetic and semi-synthetic. Molybdenum disulfide particles form an additional lubricating layer on the surfaces of parts, which protects them from abrasive wear, scuffing and corrosion.

If the base oil evaporates, MoS2 takes over the lubricating function, and the lubricant begins to work as an emergency lubricant.

Molybdenum lubricants have a high load-bearing capacity and can operate under very heavy loads. As a rule, they are laid for the entire service life of the wheel bearing.

The disadvantage of molybdenum materials is that with prolonged exposure to water, abrasive particles are formed in them, which negatively affect the condition of the bearings. Therefore, if their tightness is compromised, the lubricant needs to be replaced.
