Solution

1. Preparation

Gather tools and parts required for inspection and repair.
Ensure the vehicle is parked on a level surface and securely raise it using jack stands.
Disconnect the battery to prevent any electrical issues during repairs.

2. Inspect and Replace CV Joints

Sub-steps:
1. Remove the wheel of the affected side using a socket set.
2. Inspect the CV joint boot for tears or grease leakage. If damaged, proceed to replace the CV joint.
3. Use a torque wrench to remove the axle nut and disconnect the CV joint from the hub.
4. Replace the CV joint with a new one, ensuring it is properly greased.
5. Reinstall the axle nut to manufacturer specifications (typically around 150 ft-lbs).
6. Reattach the wheel and lower the vehicle.

3. Inspect Wheel Bearings

Sub-steps:
1. With the wheel removed, check for any play in the wheel hub by shaking it side to side.
2. If play is detected, remove the hub assembly and replace the wheel bearings.
3. Clean the bearing surfaces and apply fresh grease before reassembly.
4. Reinstall the hub assembly and torque the retaining bolts as per the specifications.

4. Inspect Suspension Components

Sub-steps:
1. Inspect the control arms, bushings, and other suspension components for wear or damage.
2. Replace any worn-out bushings or components as needed.
3. Ensure all bolts are tightened to the manufacturer’s torque specifications.
