Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to prevent electrical shorts.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Inspect and Replace Power Steering Fluid

Sub-steps:
1. Remove the power steering fluid reservoir cap.
2. Inspect the fluid for color and contamination; it should be clear amber. If dark or murky, proceed to change it.
3. Use a siphon or turkey baster to remove old fluid from the reservoir.
4. Refill with the manufacturer-recommended power steering fluid (Toyota PS fluid).
5. Replace the cap securely.

3. Inspect and Replace Power Steering Pump (If Noisy)

Sub-steps:
1. Disconnect the power steering fluid lines from the pump (use a line wrench).
2. Remove the pump mounting bolts using a socket set.
3. Carefully remove the pump from the engine bay.
4. Install the new power steering pump by reversing the removal steps.
5. Reconnect the fluid lines and ensure they are tight to prevent leaks.

4. Inspect and Replace Power Steering Belt

Sub-steps:
1. Locate the power steering belt and check for fraying, cracks, or signs of wear.
2. If damaged, loosen the tensioner pulley to relieve tension.
3. Remove the old belt from the pulleys.
4. Route the new belt according to the diagram usually found near the engine bay.
5. Tighten the tensioner pulley to the manufacturer's specification.

5. Final Checks

Start the engine and let it idle for a few minutes.
Turn the steering wheel from lock to lock several times to bleed air from the system.
Recheck the fluid level and top off if necessary.
