Solution

1. Preparation

Gather all required tools and parts.
Park the vehicle on a level surface and turn off the engine.
Disconnect the negative battery terminal for safety.

2. Check and Refill Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and check the fluid level; it should be between the "MIN" and "MAX" marks.
If low, add the recommended power steering fluid (typically ATF or PS fluid specific to Toyota).

3. Inspect and Replace the Drive Belt (if necessary)

Use a socket set to loosen the tensioner pulley and remove the old drive belt if it shows wear.
Replace it with a new belt, ensuring proper alignment on all pulleys.
Tighten the tensioner to the manufacturer's specifications.

4. Bleed the Power Steering System

With the engine off, turn the steering wheel from lock to lock several times to expel air.
Start the engine and repeat the process while checking fluid levels, adding fluid as necessary.
Monitor for any further noise during this process.

5. Replace the Power Steering Pump (if needed)

Remove the drive belt from the power steering pump.
Disconnect the power steering lines using appropriate wrenches.
Unbolt the power steering pump from its mounting bracket.
Install the new pump by reversing the removal steps, ensuring all connections are tight.
Refill the power steering system with fluid.
