2. Drain Power Steering Fluid

Place a fluid catch pan under the power steering pump.
Remove the power steering fluid reservoir cap.
Disconnect the return hose from the reservoir and allow the fluid to drain completely.

3. Inspect and Replace Components

A. Power Steering Pump

Remove the old pump:
- Disconnect the power steering pump from its mounting bracket using socket wrenches.
- Disconnect the inlet and outlet hoses from the pump and inspect for wear.
Install the new pump:
- Connect the new pump to the inlet and outlet hoses, ensuring they are tightened securely.
- Bolt the new pump back onto its mounting bracket.

B. Power Steering Hoses

Inspect and replace hoses if necessary:
- If any hoses are cracked or damaged, loosen the clamps and remove them.
- Install new hoses, making sure they are properly secured and tightened.

C. Steering Rack

Inspect for leaks:
- If the steering rack is leaking, it may require a rebuild or replacement.
- Remove the steering rack (this may require additional disassembly of front suspension components).
- Install the new or rebuilt steering rack, ensuring all connections are tight.

4. Refill Power Steering Fluid

Fill the power steering reservoir with the recommended power steering fluid.
Start the engine and turn the steering wheel from lock to lock several times to purge air from the system.
Check the fluid level again and add more fluid if necessary.

5. Final Check

Reconnect the negative battery cable.
Inspect for any signs of leaks around the pump, hoses, and steering rack.
