Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to avoid electrical issues during inspection.

2. Inspect Power Steering Fluid

Sub-steps:
- Locate the power steering fluid reservoir.
- Check the fluid level against the dipstick markings.
- If low, top off with the recommended power steering fluid (Toyota PS Fluid or equivalent).
- Inspect fluid for discoloration or debris; if contaminated, proceed to fluid replacement.

3. Check for Leaks

Sub-steps:
- Visually inspect all hoses and connections for leaks.
- Clean any residue on hoses and fittings and recheck for leaks after running the engine.
- If leaks are present, replace the affected hoses or fittings.

4. Inspect Steering Rack and Pinion

Sub-steps:
- Raise the front of the vehicle using a jack and secure it with jack stands.
- Visually inspect the steering rack for any signs of damage or fluid leaks.
- Check the mounting points for security and tightness.

5. Test Steering Pump

Sub-steps:
- Start the engine and listen for any unusual noises from the steering pump.
- Turn the steering wheel from lock to lock while parked and check for responsiveness and smoothness.
- If the pump is noisy or performance is lacking, consider replacing the power steering pump.

6. Inspect Steering Components

Sub-steps:
- Check the tie rods and ball joints for signs of wear by moving them back and forth.
- If excessive play or wear is detected, replace the worn components.
- Reassemble all parts and ensure all fasteners are tightened to the manufacturer’s specifications.
