Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative battery terminal.
Tools required: Socket set, wrench set, fluid catch pan.

2. Check and Top Off Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level. If low, add the appropriate power steering fluid until it reaches the recommended level.
Inspect the fluid condition; if it appears dirty or contaminated, consider a fluid flush.

3. Inspect and Replace Faulty Components

Steering Rack and Pinion:
- Inspect the steering rack for leaks or damage.
- If damaged, disconnect the steering linkage and fluid lines, then remove the steering rack. Replace with a new or remanufactured unit.
Tie Rod Ends and Ball Joints:
- Check for play in tie rod ends and ball joints by wiggling them.
- If worn, use a socket to remove the nuts and replace with new parts.
Bushings:
- Inspect all bushings for deterioration. If worn, use a bushing press or appropriate tools to replace them.

4. Reassembly

Reconnect all components securely and ensure all fasteners are torqued to manufacturer specifications.
Refill the power steering fluid reservoir and bleed the system if necessary (turning the steering wheel from lock to lock with the engine running).

5. Final Checks

Reconnect the negative battery terminal.
Start the vehicle and check for any leaks or noises during steering input.
