Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Wheel Bearings (if necessary)

Raise the Vehicle: Use a jack to lift the front of the car and secure it on jack stands.
Remove the Wheel: Use a socket set to remove the lug nuts and take off the wheel.
Check Wheel Bearing: Spin the hub and listen for grinding or roughness.
Remove Hub Assembly:
- Remove the brake caliper and rotor.
- Use a socket set to remove the hub assembly bolts.
- Carefully pull the hub off the spindle.
Replace Bearing: If the bearing is damaged, press out the old bearing and press in a new one.
Reassemble: Reverse the disassembly steps to reassemble the hub, rotor, and caliper.

3. Inspect and Replace CV Joints (if necessary)

Access CV Joint: If the CV joint is suspected, remove the wheel and hub as previously described.
Check CV Boot: Inspect for tears or grease leakage.
Remove Axle: If the CV joint is damaged, remove the axle from the transmission and the wheel hub.
Replace CV Joint: Use a CV joint removal tool to separate the joint from the axle and install a new joint.
Reassemble: Reinstall the axle and hub, ensuring all bolts are torqued to manufacturer specifications.

4. Inspect and Replace Steering Components (if necessary)

Check Tie Rods: With the vehicle raised, visually inspect the tie rods for play.
Replace Tie Rods: If damaged, remove the tie rod end from the steering rack and the spindle.
Reassemble: Install new tie rods and adjust the alignment as necessary.
