Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Lift Vehicle

Use a jack to lift the front or rear of the vehicle as needed.
Secure the vehicle on jack stands for safety.

3. Inspect CV Joints

Remove the wheel assembly to gain access to the CV joint.
Visually inspect the CV joint for any signs of wear or damage.
Check the condition of the CV boot for any tears or leaks.

4. Replace Damaged CV Joint

Remove the Axle Nut:
- Use a socket set to remove the axle nut that secures the CV joint to the wheel hub.
- Torque value: Typically around 200 Nm but check the service manual for exact specifications.
Detach the CV Joint:
- Use a puller or a hammer to gently detach the CV joint from the hub if necessary.
Replace the CV Joint:
- If the CV joint is damaged, remove it from the axle shaft by removing any retaining clips.
- Install the new CV joint by sliding it onto the axle shaft and securing it with the retaining clip.

5. Reassemble Components

Reattach the CV joint to the wheel hub and torque the axle nut to specifications.
Reinstall the wheel and lower the vehicle back to the ground.

6. Final Check

Ensure all tools are removed from the engine bay and check fluid levels if necessary.
