Installing the hub
Signs of a damaged rear wheel bearing include extraneous noise that occurs when the speed reaches a certain value.
The rear wheel bearings consist of two high-precision ball bearings. The bearing is located in the wheel hub, to which the brake drum and brake disc are attached. The bearing is installed in place using a special mandrel and a press. Therefore, it is advisable to remove the hub with the bearing and install a new bearing in a specialized workshop to install the bearing.
Examination
Loosen the wheel nuts on a vehicle parked on the ground.
Mark the position of the wheel disk relative to the hub to enable installation of a balanced wheel in the same place.
Raise the rear of the vehicle.
Remove the rear wheel.
Turn the brake drum and brake disc by hand with the handbrake released. The bearing should rotate easily and smoothly.
Remove the brake drum with the brake disc.
In a specialized workshop, the axial play in the wheel hub is measured using a dial indicator. The axial play should not exceed 0.05 mm. If the play is greater, replace the bearing. If you have experience, the axial play can also be determined manually by moving the hub by hand in both directions.
