Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to ensure safety.

2. Inspect and Replace CV Joints (if necessary)

Sub-steps:
1. Lift the front of the vehicle using a jack and secure it on jack stands.
2. Remove the front wheel on the affected side using a socket set.
3. Inspect the CV joint boot for any tears; if damaged, replace the joint.
4. Remove the retaining clips and detach the CV joint from the axle shaft.
5. Install the new CV joint by reversing the removal process, ensuring proper torque specifications are followed (typically 30-40 lb-ft for retaining bolts).

3. Inspect and Replace Strut Mounts and Bushings (if necessary)

Sub-steps:
1. Remove the strut assembly by loosening the top strut nuts under the hood and the lower strut bolts.
2. Inspect the strut mount and bushings for wear or cracking; replace if necessary.
3. Install new strut mounts and bushings, ensuring they are properly seated.
4. Reinstall the strut assembly, tightening the bolts to manufacturer’s torque specifications (usually 60-80 lb-ft).

4. Check and Replace Wheel Bearings (if necessary)

Sub-steps:
1. After removing the wheel, check for play in the wheel bearing by wiggling the wheel.
2. If there is excessive play, remove the brake caliper and rotor.
3. Use a bearing puller to remove the old bearing.
4. Install the new bearing and reassemble the brake components, ensuring proper torque.
