Solution

1. Preparation

Gather tools and materials.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety glasses and gloves.

2. Inspect CV Joints

Sub-steps:
1. Lift the front of the vehicle using a jack and secure it with jack stands.
2. Remove the front wheels using a socket set.
3. Inspect the outer and inner CV joints for torn boots or grease leakage.
4. If damaged, proceed to replace the affected CV joint.

3. Replace Affected CV Joint

Sub-steps:
1. Remove the axle nut using a socket and breaker bar.
2. Disconnect the lower control arm from the knuckle to free the axle.
3. Pull the axle out from the transmission side.
4. Install the new CV joint or axle, ensuring it is seated properly.
5. Reattach the lower control arm and torque the bolt to the manufacturer’s specifications (typically around 60-80 Nm).
6. Reinstall the axle nut and torque it to the manufacturer’s specifications (typically around 200 Nm).

4. Test Drive

After the repair, lower the vehicle and test drive to ensure the clicking noise is resolved.
