Lada Granta front wheel bearing replacement. Photo and video instructions

One day, the owner of a Lada Grant will experience an unpleasant failure of the bearing on the front hub. It is necessary to take timely measures, and at the same time the front wheel bearing is replaced, and if this is not done, then you can get away with significantly lower costs. And when the owner neglects the timeliness factor and postpones repairs, he automatically falls into the cohort of “provocateurs” of an accident, because the failure of this unit while driving can have dire consequences.

The main purpose of the bearing is to ensure the retention of the hub and rotation of the Lada Granta wheel. The design of the element we are considering provides for the presence of the following components:

• outer and inner races (metal);
• separator with balls or rollers;
• insulating rings to ensure protection of the working area of ​​the product;
• lubricant.

The primary factors that make it possible to diagnose a malfunction of the hinge mechanism include the following:

• the occurrence of extraneous noise coming from a specific wheel in motion;
• wheel runout or manifestation of vibrational nature of rotation;
• sounds resembling grinding, as well as wheel play.

If such faults are present in your car, the front wheel bearing needs to be replaced.

Causes of malfunctions

The resource of this part is very impressive and can reach 100 thousand km, subject to gentle operation. Modern realities show that the front hub bearing can become unusable much earlier than the specified regulatory period.

Next, we will identify three significant factors that can cause premature wear of a part such as the front wheel bearing in a Lada Granta car.

1. The state of domestic roads, the quality of which is far from ideal. When driving over bumps, the front wheel bearing experiences enormous stress. Also, critical temperatures and dynamic impacts (shocks) can have a negative impact on their condition. All this leads to the structure of the material from which the front hub bearing is made losing its strength properties, which provokes destructive processes.
2. Exposure to aggressive environments. Due to the structural location of the bearing, it is doomed to constant contact with moisture, dirt and other negative atmospheric factors. The influence of heat and cold is also detrimental to his condition.
3. Increased operating temperature. During the rotation process, natural heat generation occurs. Temperature changes, especially in winter, also have a detrimental effect on the strength parameters of the product.

Resource for replacing hub mechanism elements

The average service life of wheel joints is 80 – 85 thousand km. The indicator is average, as it depends on the following factors:

• quality of workmanship of the part;
• frequency of operation of the technical device;
• driving style;
• quality of road surface;
• aggressive environment;
• high operating temperatures;
• compliance with technical inspection intervals.

Signs that a hub needs to be replaced

• the appearance of uncharacteristic noise during wheel rotation;
• wheel runout in the steering column;
• vibrations at different speeds. Sometimes there is vibration at a certain speed;
• metallic grinding noise as the wheel rotates;
• front wheel hub play.

Diagnostics of the hub mechanism

1. We place the car on a level platform, squeeze the parking brake if we are checking the front row. For the rear, we install wheel chocks.
2. Let's jack up the front (rear) part.
3. We turn the car wheel and carry out troubleshooting.
4. We shake the wheel up and down with our hands. In good condition there should be no play. Otherwise, we dismantle and replace worn elements.
