Solution

1. Preparation

Gather tools and materials needed for repair.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Check and Replace Power Steering Fluid

Sub-steps:
1. Locate the power steering fluid reservoir.
2. Remove the cap and check the fluid level; if low, add the recommended type of fluid (typically ATF or specific PS fluid).
3. If fluid is dirty or contaminated, drain the system using a turkey baster and refill with fresh fluid.

3. Inspect and Replace Power Steering Pump

Sub-steps:
1. Disconnect the negative battery terminal.
2. Remove the serpentine belt using a belt tensioner tool.
3. Unbolt the power steering pump from its mount.
4. Disconnect the fluid lines from the pump; use a container to catch any residual fluid.
5. Remove the old pump and install the new pump by reversing the removal steps.
6. Reconnect the fluid lines and ensure they are secure.
7. Reinstall the serpentine belt, ensuring proper routing and tension.

4. Inspect the Steering Rack

Sub-steps:
1. Raise the front of the vehicle using jack stands.
2. Inspect the steering rack for any signs of leaks or damage.
3. If damaged, unbolt the steering rack from its mounts and disconnect it from the steering column.
4. Install a new steering rack and reassemble.

5. Final Reassembly and Fluid Check

Sub-steps:
1. Reconnect the negative battery terminal.
2. Start the engine and turn the steering wheel from lock to lock to bleed air from the system.
3. Check the power steering fluid level again and top off as necessary.
