Gather tools and parts required.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal for safety.

2. Check Power Steering Fluid

Tools Required: Fluid container, funnel
Remove the power steering fluid reservoir cap.
Check the fluid level against the indicator marks. If low, add the recommended power steering fluid (Toyota ATF Type T-IV).
Inspect fluid for discoloration or debris, indicating contamination.

3. Inspect Power Steering Pump

Tools Required: Wrench set, flashlight
Locate the power steering pump (usually mounted on the front of the engine).
Check the pump for any visible signs of leaks or damage.
Listen for unusual sounds when the engine is running; a noisy pump may need replacement.

4. Examine Steering Rack

Tools Required: Wrench set, jack and jack stands
Raise the vehicle securely using jack stands.
Inspect the steering rack for leaks or physical damage.
Check for looseness or wear in the mounting points and connections.

5. Inspect Drive Belt

Tools Required: Wrench set, tension gauge (if applicable)
Locate the drive belt connected to the power steering pump.
Check the belt for signs of wear, cracks, or fraying.
Ensure proper tension; adjust or replace if necessary.

6. Inspect Wheel Bearings

Tools Required: Jack and jack stands, wheel chocks
Lift the vehicle and remove the front wheels.
Check for play in the wheel bearings by rocking the wheel back and forth.
If play is detected, the wheel bearings may need to be replaced.
