Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Check Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check fluid level; top up with the recommended fluid (Toyota ATF WS) if low.
Inspect fluid condition; if dirty or contaminated, proceed to fluid replacement.

3. Inspect Power Steering System for Leaks

Visually inspect hoses and connections for leaks.
Use a flashlight to check under the vehicle for any signs of fluid accumulation.
If leaks are found, identify the source (hoses, fittings, or pump) and replace the affected components.

4. Replace Power Steering Fluid (if necessary)

Place a drain pan under the power steering reservoir.
Disconnect the return line from the reservoir and allow old fluid to drain completely.
Reconnect the line, then refill the reservoir with new power steering fluid.
Start the engine and turn the steering wheel side to side to purge air from the system.

5. Inspect and Replace Power Steering Pump (if needed)

If the pump is noisy or damaged, remove it by detaching the mounting bolts and disconnecting the fluid lines.
Install the new power steering pump, ensuring all connections are secure.
Refill the power steering fluid and check for proper operation.
