Solution

1. Preparation

Tools Required: OBD-II scanner, fluid catch pan, flashlight, wrenches, rags.
Park the vehicle on a level surface and ensure the engine is off.
Gather necessary tools and parts.

2. Locate and Fix Leaks

Inspect Hoses:
- Remove any plastic covers as needed to access the power steering fluid hoses.
- Tighten loose hose clamps or replace damaged hoses as necessary.
Replace Power Steering Pump (if leaking):
- Disconnect the negative battery terminal.
- Drain the power steering fluid into a catch pan.
- Remove the drive belt from the power steering pump.
- Unbolt and remove the power steering pump from its mounting.
- Install the new pump in reverse order, tightening bolts to manufacturer specifications (typically around 14-20 ft-lbs).

3. Replace Steering Rack (if necessary)

Remove and Replace:
- Disconnect the battery and drain fluid.
- Remove the tie rod ends from the steering rack.
- Unbolt the steering rack from the subframe and disconnect any electrical connectors.
- Install the new steering rack, ensuring all connections are secure and torqued to specifications (generally 37-45 ft-lbs).

4. Refill and Bleed System

Refill the power steering reservoir with the correct type of power steering fluid (usually ATF or a specific power steering fluid).
Start the engine and turn the steering wheel from lock to lock several times to bleed air from the system.
