Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the 12V battery to ensure safety while working on electrical components.

2. Inspect and Replace Power Steering Fluid

Check the power steering fluid reservoir for low levels.
- If low, top off with manufacturer-recommended fluid.
If fluid appears contaminated, drain and replace the fluid.
- Use a siphon pump to remove old fluid from the reservoir.
- Refill with new power steering fluid until it reaches the appropriate level.

Inspect the steering rack and associated links for any visible damage.
If damaged, remove the steering rack:
- Loosen and remove the bolts securing the steering rack to the subframe.
- Disconnect the steering shaft from the rack and remove it from the vehicle.
Replace with a new steering rack if necessary, following manufacturer specifications for installation.

4. Alignment Adjustment

After repairs, perform a wheel alignment:
- Use an alignment machine to adjust the toe, camber, and caster settings to factory specifications.
Confirm that the steering wheel is centered during this process.

5. Reconnect Battery and Test Drive

Reconnect the 12V battery.
Start the vehicle and check for any warning lights related to the steering system.
Conduct a test drive to assess steering response and ensure the issue is resolved.
