Solution

1. Preparation

Gather tools and parts. Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Tools Required:
- Socket set
- Torque wrench
- Fluid catch pan
- Power steering fluid
Safety Warnings:
- Disconnect the battery before working on electrical components.
- Allow the vehicle to cool before inspecting the power steering system.

2. Check and Refill Power Steering Fluid

Remove the power steering fluid reservoir cap.
Inspect the fluid level. If low, top off with the recommended power steering fluid.
Inspect the fluid for contamination (dark color or debris). If contaminated, proceed to replace the fluid.

3. Inspect Power Steering Pump

Locate the power steering pump.
Disconnect the power steering pump pulley using a socket set.
Remove the pump and inspect for noise during manual rotation. If noisy, replace the pump.
Reinstall the new pump and torque to manufacturer specifications.

4. Inspect Steering Rack

Check the steering rack for any visible leaks or damage.
If the steering rack is leaking or damaged, remove it by disconnecting the tie rods and fluid lines.
Replace with a new or remanufactured steering rack, ensuring proper alignment during installation.

5. Inspect CV Joints and Axles

Raise the vehicle and support it securely.
Inspect the CV joints for torn boots or excessive play.
If damaged, replace the CV joint or axle assembly as necessary.

6. Inspect Wheel Bearings

Rotate the wheel and listen for grinding noises.
If bearings are rough or have excessive play, replace them using appropriate removal and installation techniques.
