Solution

1. Preparation

Gather necessary tools and parts.

Disconnect the battery to ensure safety.

2. Check Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check fluid level; if low, add the recommended fluid type (Toyota PSF).
Inspect for signs of contamination or burnt smell in the fluid.

Visually inspect hoses and connections for signs of fluid leakage.
Use a flashlight to check areas around the power steering pump and steering rack.
If leaks are found, identify and replace the faulty hose or component.

4. Test Power Steering Pump

Reconnect the battery and start the engine.
Turn the steering wheel from lock to lock, listening for any unusual noises.
Use a pressure gauge to check the pump output; it should meet manufacturer specifications.

5. Examine Steering Components

Lift the front of the vehicle using a jack and secure with jack stands.
Inspect the steering rack for play or excessive movement.
Check tie rods and ball joints for wear or damage; replace if necessary.

6. Wheel Alignment

Have a professional perform a wheel alignment to ensure proper steering geometry.
Adjust toe, camber, and caster angles as needed according to specifications.
