Solution

1. Preparation

Tools Needed: Jack and jack stands, socket set, torque wrench, OBD-II scanner, power steering fluid.
Ensure the vehicle is on a flat surface and engage the parking brake.

2. Inspect and Replace Steering Components

Inspect Steering Rack:
- Remove any covers obstructing access.
- Check for leaks or physical damage.
- If damaged, detach the steering rack using a socket set and replace it with a new unit.
Check and Replace Tie Rods:
- Use a tie rod end puller to remove the tie rod end from the steering knuckle.
- Replace with a new tie rod, ensuring proper torque specifications (usually around 45-55 lb-ft).
Inspect Power Steering Pump:
- Remove the power steering pump belt.
- Check for any signs of wear and replace if necessary.
- Refill power steering fluid as needed and bleed the system according to manufacturer specifications.

3. Wheel Alignment

Adjust Wheel Alignment:
- Use an alignment machine to check and adjust the camber, caster, and toe angles to factory specifications.
- Ensure all adjustments are properly torqued as per specifications.

4. System Reset (If applicable)

If electronic steering issues were detected, perform a reset using the OBD-II scanner to clear any fault codes.
