Sequence of work
1. Take turns holding the wheels on the ground at the top and try to rock them in a direction transverse to the car.
2. With serviceable bearings, there should be practically no play.
3. If play is present, ask an assistant to apply the brake and shake the wheel again. If the backlash has disappeared, then its cause is the wheel bearing. If it is preserved, it is necessary to check the wheel suspension.
4. Failed rear wheel bearings must be replaced.
