Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative terminal of the battery for safety.

2. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level.
If low, add the recommended type of power steering fluid until it reaches the proper level. Use Toyota Genuine ATF or equivalent.

3. Inspect and Replace Power Steering Pump (if necessary)

Remove the Belt:
- Loosen the tensioner pulley and remove the serpentine belt from the power steering pump.
Disconnect Hoses:
- Place a drain pan under the power steering pump.
- Disconnect the high and low-pressure hoses using a wrench.
Remove the Pump:
- Unbolt the power steering pump from its mounting bracket using a socket set.
Install New Pump:
- Position the new power steering pump in place and secure it with bolts to the mounting bracket.
- Reconnect the high and low-pressure hoses, ensuring they are tight and leak-free.

4. Bleed the Power Steering System

With the vehicle running, turn the steering wheel from lock to lock several times to remove air from the system.
Check the fluid level again and add fluid as necessary.

5. Reconnect Battery

Reconnect the negative terminal of the battery securely.
