Solution

1. Preparation

Park the vehicle on a level surface and engage the parking brake.
Wear safety goggles and gloves.
Gather necessary tools and parts.

2. Inspect Steering Linkage

Tools Required: Socket set, torque wrench
Remove the splash shield if necessary for access.
Inspect the tie rod ends for wear and ensure they are securely fastened.
Check the steering rack for any visible damage or looseness.

3. Check CV Joints

Tools Required: Jack, jack stands, and a socket set
Raise the front of the vehicle using a jack and secure it with jack stands.
Inspect the CV boots for any tears or leaks. If damaged, replace the CV joint.
Rotate the front wheels manually to listen for any clicking noises.

4. Examine Suspension Components

Tools Required: Wrench set
Inspect control arms and bushings for wear or damage. Replace any worn components.
Check for any loose bolts or nuts in the suspension setup and tighten to the manufacturer's specifications.

5. Inspect Wheel Bearings

Tools Required: Torque wrench
Check for play in the wheel bearings by rocking the wheel back and forth. If movement is detected, the wheel bearing may need replacement.
Re-torque wheel bearing nuts to the manufacturer’s specifications if they were loosened during inspection.

6. Check Power Steering System
