Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the vehicle’s battery for safety.

2. Inspect and Secure Components

Check for Loose Bolts:
- Inspect all undercarriage bolts and fasteners for tightness.
- Use a socket set to tighten any loose bolts to manufacturer specifications.
Examine Drive Axles:
- Lift the vehicle using a jack and secure it with jack stands.
- Inspect the CV boots for tears or leaks. Replace if necessary.

3. Replace Damaged Components

CV Joint Replacement (if needed):
- Remove the wheel and brake components to access the CV joint.
- Use a socket set to detach the CV joint from the transmission.
- Install the new CV joint and reassemble in reverse order, ensuring all bolts are torqued to specifications.

4. Reassemble and Test

Reattach any components removed during inspection or repair, ensuring proper alignment.
Reconnect the vehicle’s battery.
Lower the vehicle and perform a test drive to check for the elimination of the clicking noise.
