Solution

1. Preparation

Gather necessary tools and parts.
Lift the vehicle using a jack and secure it with jack stands.
Ensure the vehicle is on a level surface.

2. Inspect Power Steering Fluid

Remove the power steering fluid reservoir cap.
Check the fluid level; it should be between the "MIN" and "MAX" marks.
If low, top off with the manufacturer-recommended fluid (Toyota PSF).

3. Check Steering Components

Steering Rack:
- Inspect for leaks and physical damage.
- Ensure all mounting bolts are tight. Torque specifications can usually be found in the service manual.
Tie Rod Ends:
- Check for play by moving the tie rod up and down.
- If there is excessive play, replace the tie rod ends.

4. Inspect Wheel Bearings

Spin the wheel by hand; listen for grinding noise.
If noise is present, remove the wheel and inspect the bearing.
Replace the bearing if it feels rough or has excessive play.

5. Examine Ball Joints and Suspension

Check ball joints for any signs of wear or looseness.
Inspect bushings and other suspension components for deterioration.
Replace any worn components identified.
