Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Replace CV Joints

Tools Required: Socket set, torque wrench, pry bar, CV joint puller (if necessary).
Remove the wheel on the side where the clicking occurs.
Inspect the CV joint for damage or wear. Look for torn boots or grease leakage.
If the CV joint is damaged, remove it by:
1. Disconnecting the axle nut with a socket.
2. Using a pry bar to pop the CV joint out of the transmission.
3. Installing the new CV joint by reversing the removal steps and ensuring the axle nut is torqued to manufacturer specifications (typically around 150 Nm).

3. Inspect Steering Components

Tools Required: Torque wrench, socket set, suspension tool kit.
With the vehicle still raised, check the tie rod ends for play:
1. Use a pry bar to apply leverage and check for movement.
2. If worn, replace the tie rod ends by:
  - Loosening the retaining nut and separating the tie rod from the steering knuckle using a puller.
  - Installing the new tie rod end and torqueing it to the manufacturer’s specifications.
Inspect the steering rack:
1. Look for leaks and ensure all mounting bolts are tight.
2. Replace the steering rack if any internal damage is found.

4. Check Suspension Components

Tools Required: Wrench set, jack stands.
Examine control arms and bushings for wear:
1. Look for cracks or separation in the rubber bushings.
2. Replace any damaged bushings or control arms by:
  - Removing the bolts securing them to the chassis and suspension.
  - Installing new parts and torqueing them to specifications.
