Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Ensure the engine is off and cool.
Tools Required: Jack and jack stands, socket set, torque wrench, OBD-II scanner.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which CV joint you are inspecting.
Secure the vehicle with jack stands to ensure safety.

3. Remove Wheel

Loosen the lug nuts with a socket wrench.
Remove the wheel to access the CV joint and axle.

4. Inspect CV Joint Boots

Examine the CV joint boots for any signs of cracking, splitting, or grease leakage.
If the boots are damaged, they must be replaced.

5. Test CV Joint Functionality

Manually move the axle shaft to check for excessive play or movement.
Listen for any clicking or popping noises while rotating the axle by hand.

6. Replace CV Joint (if necessary)

If the CV joint is damaged:
- Remove the retaining clip and any bolts securing the joint.
- Slide the old CV joint off the axle shaft.
- Clean the axle shaft and install new grease.
- Slide the new CV joint onto the axle shaft and secure it with a new retaining clip and bolts.
- Torque values: Refer to the service manual for the correct torque specifications.

7. Reassemble and Lower Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and torque the lug nuts to the manufacturer’s specifications.
