Checking the play of the front suspension wheel bearings (Audi 100 C4)

The front wheels move on double-row ball bearings, and the rear wheels on radial tapered roller bearings. They can withstand a mileage of more than 100,000 km with grease on the rear axle. The front wheel bearings can already attract attention much earlier due to noise. If the noise becomes stronger, for example, when turning right, then the defect is in the left bearing.

Take a firm grip on the wheel standing on the ground at the top and try to move it in a perpendicular direction.

If the bearings are in good condition, there should be virtually no play.

If the play is noticeable, you need to ask an assistant to press hard on the brakes and pump the wheel again.

If the play is no longer felt, then the play is only in the wheel bearing. If there is play on the braked wheel, the suspension must be checked.

If play is found in the rear wheel bearings, it can be adjusted.

Raise and support the car and check the wheel: if it moves with difficulty or jerks, the bearing is adjusted too tightly. If a distinct "grinding" sound is heard, the bearing must be replaced.
