Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical issues.

2. Check Fluid Level

Locate the power steering reservoir.
Remove the cap and check the fluid level against the markings on the reservoir.
If low, add the recommended power steering fluid (Toyota ATF WS or equivalent).

3. Inspect and Repair Hoses

Visually inspect all power steering hoses for cracks, holes, or loose connections.
If any hoses are damaged, replace them:
- Use a socket set to remove hose clamps.
- Replace with OEM hoses and tighten clamps to the manufacturer's specifications.

4. Replace Power Steering Pump (if necessary)

Remove the serpentine belt from the power steering pump:
- Use a wrench to relieve tension on the belt tensioner and slide the belt off.
Disconnect the power steering lines from the pump using a wrench.
Unbolt the pump from its mounting bracket using a socket set.
Install the new power steering pump:
- Reverse the removal steps, ensuring all bolts are tightened to the specified torque value.
- Reconnect the power steering lines securely.

5. Bleed the Power Steering System

Fill the power steering reservoir with fluid.
Start the engine and turn the steering wheel from lock to lock several times to bleed air from the system.
Check fluid levels again and top off if necessary.
