Solution

1. Preparation

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

2. Inspect and Top Off Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and check fluid level; if low, add the recommended power steering fluid (check owner’s manual for specifications).
Inspect fluid for contamination (milky appearance indicates water contamination).

3. Identify and Repair Leaks

Visually inspect hoses and connections for signs of fluid leaks.
Tighten any loose connections.
If leaks are found, replace damaged hoses or seals.

4. Test and Replace Power Steering Pump (if necessary)

Connect a pressure gauge to the power steering pump outlet.
Start the engine and observe pressure readings; compare with manufacturer specifications.
If pressure is low, remove the pump:
- Disconnect the hoses and electrical connector.
- Unbolt the pump from its mounting bracket.
- Install the new power steering pump and reconnect hoses and electrical connector.

5. Inspect and Replace Steering Rack (if necessary)

Remove the steering rack:
- Disconnect the steering linkage from the rack.
- Remove any mounting bolts securing the rack to the subframe.
- Disconnect the power steering lines.
Install the new steering rack and reverse the removal steps.

6. Recheck Fluid and System Functionality

Refill the power steering fluid as needed.
Start the vehicle and turn the steering wheel from lock to lock several times to bleed air from the system.
Check for leaks and ensure smooth steering operation.
