To check the condition of the wheel bearings, you need to hang the wheel and rotate it by hand

The wheel should rotate evenly, without jamming or knocking

We take the wheel in a vertical plane and alternately pull the upper part toward us, and the lower part away from us, and vice versa. We make sure there is no play.

Usually, when driving, a “squealing” sound is heard from a faulty wheel bearing.

Raise the rear of the car and place a safety device.

Unscrew and remove the rear wheel. Fully lower the parking brake lever. We loosen the tension of the parking brake cables.
