Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspecting Suspension Components

Tools Required: Socket set, torque wrench, flashlight.
Remove the front wheel using a socket set.
Inspect control arms, bushings, and struts for any visible signs of damage or wear.
If any components are damaged, proceed to replace them.

3. Checking CV Joints and Axles

Tools Required: CV joint removal tool, socket set.
Inspect the outer and inner CV boots for tears or leaks.
If the boot is damaged, replace the CV joint assembly.
Ensure that the axles are securely mounted and have no excessive play.

4. Examining the Steering Rack

Tools Required: Socket set, torque wrench.
Remove any covers or shields to access the steering rack.
Check for any leaks or loose connections.
If the rack is loose, tighten the bolts to the manufacturer's specifications.
