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 to ensure safety.

2. Fluid Inspection and Replacement

Remove the power steering reservoir cap.
Check the fluid level; if low, add the recommended power steering fluid.
If the fluid is dirty or contaminated, proceed to replace it.
- Tools Required: Fluid pump, clean funnel, container for old fluid.
- Safety Warning: Avoid skin contact with power steering fluid; it can be harmful.

3. Leak Repair

Identify the source of any leaks by following the fluid trail.
If a hose is leaking, disconnect the hose using a wrench and replace it with a new one.
For a leaking steering rack, remove the rack from the vehicle:
- Disconnect any electrical connectors and steering linkages.
- Unbolt the steering rack from its mounts and remove it.
- Replace it with a new or remanufactured steering rack.
- Torque Specifications: Refer to vehicle service manual for specific torque values when re-installing the steering rack.

4. Component Inspection and Replacement

Inspect tie rod ends and ball joints for wear:
- If any play is detected, remove the old components and replace them.
- Tools Required: Socket set, torque wrench.
Reassemble all components and ensure everything is tightened to factory specifications.

5. Steering Alignment

Once repairs are complete, take the vehicle for a professional wheel alignment to ensure proper handling and prevent uneven tire wear.
