Solution

1. Preparation

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

2. Check Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; top off with manufacturer's recommended fluid if low.
Inspect fluid condition; if dirty, consider flushing the system.

3. Inspect CV Joints

Raise the front of the vehicle using a jack and secure with jack stands.
Remove the wheel to access the CV joint.
Inspect the CV boots for tears or leaks; replace if necessary.
Check the CV joint for excessive play or grinding; replace if damaged.

4. Inspect Wheel Bearings

Rotate the wheel by hand and listen for grinding noises.
Check for play by rocking the wheel in and out; replace bearings if there's excessive movement.
If bearings are worn, remove the hub assembly and replace them.

5. Check Steering Rack and Suspension

Inspect the steering rack for leaks and binding; replace if necessary.
Examine suspension components for cracks or damage; replace bushings or control arms if needed.
Reassemble all components and wheels, ensuring all fasteners are torqued to specifications.
