Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety during repair.

2. Identify Leak Source

Use a flashlight to inspect the power steering pump, hoses, and rack for signs of leaks.
If using UV dye, add it to the fluid, run the engine briefly, and use a UV light to locate the leak.

3. Replace Damaged Components

Power Steering Pump:
- Remove the drive belt from the power steering pump using a socket set.
- Disconnect the power steering lines from the pump using a wrench, and remove the pump mounting bolts.
- Install the new pump by reversing the steps, ensuring to torque bolts to the manufacturer's specifications (usually around 15-25 ft-lbs).
Hoses:
- If hoses are damaged, remove the clamps and disconnect the hoses from the pump and steering rack.
- Install new hoses, securing them with new clamps and ensuring a tight fit.

4. Refill Power Steering Fluid

After replacing components, refill the power steering reservoir with the appropriate fluid (typically ATF or specific power steering fluid recommended by Toyota).
Bleed the system by turning the steering wheel from lock to lock several times while the engine is running.

5. Reassemble and Test

Reconnect the battery and start the engine.
Check for leaks around replaced components.
Test drive the vehicle to ensure the steering system operates smoothly.
