Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent accidental electrical shorts.

2. Check Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; add fluid if low (use Toyota-approved fluid).
Inspect the fluid for contamination; if dirty, proceed to replace the fluid.

3. Inspect Power Steering Pump

Remove any components obstructing access to the power steering pump.
Check for visible leaks around the pump seals and connections.
If leaks are found, replace the power steering pump and any damaged hoses.

4. Examine Steering Rack and Linkage

Lift the vehicle using a jack and secure it with jack stands.
Inspect the steering rack and pinion for any signs of leakage or physical damage.
Check the steering linkage and tie rods for play or wear; replace any worn components.

5. Test and Replace Components

If the power steering pump or rack is faulty, replace them as necessary.
Reassemble any components removed during inspection.
Refill the power steering fluid reservoir and bleed the system to remove air.

6. Reconnect Battery and Test Drive

Reconnect the negative battery terminal.
Start the engine and turn the steering wheel from lock to lock to bleed the system.
Test drive the vehicle to ensure the steering issues are resolved.
