Solution

1. Preparation

Gather all tools and parts needed for the repair.
Safety: Ensure the vehicle is parked on a level surface, and use wheel chocks to secure it.
Disconnect the battery to prevent any electrical issues.

2. Remove Wheel and Brake Components

Sub-steps:
1. Loosen the lug nuts slightly while the vehicle is on the ground.
2. Raise the vehicle with a jack and secure it on jack stands.
3. Remove the lug nuts completely and take off the wheel.
4. Remove the brake caliper by unbolting it from the bracket (use a socket set).
5. Suspend the caliper with a wire to avoid straining the brake line.
6. Remove the brake rotor.

3. Remove and Replace Wheel Bearing

Sub-steps:
1. Remove the wheel hub assembly by unbolting it from the steering knuckle.
2. Use a bearing puller to extract the old wheel bearing from the hub.
3. Clean the hub surface thoroughly.
4. Press the new wheel bearing into the hub using a bearing press.
5. Reinstall the hub assembly onto the steering knuckle and torque the bolts to manufacturer specifications.

4. Reassemble Components

Sub-steps:
1. Reinstall the brake rotor onto the hub.
2. Reattach the brake caliper and torque the bolts to specifications.
3. Place the wheel back onto the hub and hand-tighten the lug nuts.
4. Lower the vehicle and torque the lug nuts to the recommended specifications.

5. Final Checks

Reconnect the battery.
Test the new bearing by rotating the wheel to ensure smooth operation without noise.
