Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secured with wheel chocks.
Disconnect the battery if working on electrical components.

2. Inspect Power Steering System

Check the power steering fluid:
- Remove the cap and inspect the fluid level.
- If low, top it off with the recommended fluid (consult the owner's manual for specifications).
If the fluid is dirty or contaminated, proceed to replace it.

3. Examine CV Joints and Axles

Raise the vehicle using a jack and secure it with jack stands.
Inspect the CV joints for any tears or leaks in the rubber boots.
Rotate the wheels to observe any vibrations or grinding from the CV axles.
If damaged, replace the CV joint or axle assembly.

4. Check Suspension Components

Visually inspect control arms, bushings, and struts for wear or damage.
Use a pry bar to check for excessive play in the suspension components.
Replace any worn parts as necessary, using manufacturer-specified torque values for reassembly.

5. Inspect and Repair Steering Rack

If the steering rack is suspected, remove it from the vehicle:
- Disconnect any associated electrical connectors.
- Remove the mounting bolts and carefully extract the steering rack.
Inspect for any leaks or internal damage.
Replace the steering rack if necessary and refill the power steering fluid.
