Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, socket set, wheel bearing puller.
Safety Warnings: Ensure vehicle is on a flat surface and securely supported by jack stands before working.

2. Remove Wheel

Loosen the lug nuts with a lug wrench while the vehicle is on the ground.
Jack up the vehicle and place it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Remove Brake Components

Remove the brake caliper by unbolting it; support it with a bungee cord or rope to avoid hanging by the brake line.
Remove the brake rotor by unscrewing any retaining screws and sliding it off the hub.

4. Remove the Wheel Bearing

Main Point: Use a wheel bearing puller to remove the old bearing.
Remove the hub assembly if necessary.
Follow the specific torque specifications as outlined in the vehicle’s service manual when removing bolts.

5. Install New Wheel Bearing

Clean the hub assembly and apply grease to the new wheel bearing.
Press the new bearing into place using a bearing press or appropriate tool.
Reinstall the hub assembly and ensure all bolts are tightened to the correct torque specifications.

6. Reassemble Brake and Wheel Components

Reattach the brake rotor and caliper.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.
