Solution

1. Preparation

Gather tools and safety equipment.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Inspect and Tighten Suspension Components

Sub-steps:
- Use a socket set to check the torque on all suspension bolts and nuts; refer to the service manual for correct torque specifications.
- If any bolts are loose, tighten them to the specified torque.

3. Replace Damaged Components (if applicable)

Sub-steps:
- If any suspension parts are found to be damaged (e.g., control arms, bushings), remove the affected component using a wrench and socket set.
- Install the new component, ensuring it is torqued to manufacturer specifications.

4. Inspect and Replace CV Joints (if applicable)

Sub-steps:
- If the CV joints are found to be damaged, remove the wheel and brake components to access the axle.
- Detach the axle from the differential and replace the CV joint or the entire axle assembly if necessary.
- Reassemble all components and ensure proper alignment.
