Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Replace Affected Components

Inspect Suspension Components
- Remove the wheel using a socket set.
- Check control arm bushings for cracks or wear; replace if necessary.
- Inspect the struts for leaks or damage; replace if necessary.
Check CV Joints
- Examine CV joint boots for tears or grease leakage.
- If damaged, replace the CV joint assembly.
Wheel Bearing Inspection
- Spin the wheel to listen for grinding noises indicating a bad bearing.
- If a bearing is faulty, remove the hub assembly and replace the bearings.

3. Reassembly and Testing

Reinstall any replaced components and torque bolts to manufacturer specifications (typically around 40-80 ft-lbs for suspension components; check the service manual for exact values).
Reattach the wheel and lower the vehicle to the ground.
Reconnect the negative battery terminal.
