Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, bearing puller, wheel bearing grease.
Safety Warnings: Ensure the vehicle is on a stable surface, and use jack stands to support the vehicle after lifting.

2. Remove Wheel

Loosen the lug nuts with a lug wrench while the vehicle is on the ground.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Remove Brake Components

Remove the brake caliper by unscrewing the caliper bolts with a socket set.
Hang the caliper using a bungee cord or similar to avoid straining the brake line.
Remove the brake rotor by unscrewing any retaining screws and pulling it off the hub.

4. Access Wheel Bearing

Remove the hub assembly by unscrewing the hub nut. Use a torque wrench for proper torque specifications (usually around 150 ft-lbs).
If applicable, use a bearing puller to extract the old wheel bearing from the hub assembly.

5. Install New Wheel Bearing

Clean the hub assembly and apply bearing grease to the new wheel bearing.
Press or tap the new wheel bearing into place using a bearing installation tool or appropriate socket.
Reinstall the hub assembly and secure with the hub nut, again ensuring proper torque.

6. Reassemble Brake Components

Place the brake rotor back onto the hub.
Reattach the brake caliper and secure it with the caliper bolts.
Replace the wheel and hand-tighten the lug nuts.

7. Lower Vehicle and Finalize

Lower the vehicle back to the ground and torque the lug nuts to the manufacturer’s specifications (usually around 76 ft-lbs).
Test the wheel bearing by taking a short test drive.
