Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Tire Inspection and Adjustment

Remove the hubcaps if applicable.
Check and adjust tire pressures to the specified PSI on the driver’s door jamb.
Inspect all tires for uneven wear patterns; if wear is excessive, consider tire rotation or replacement.

3. Wheel Alignment

Equipment Setup: Use a professional wheel alignment machine.
Alignment Process:
- Position the vehicle on the alignment rack and secure it.
- Connect the alignment machine sensors to each wheel.
- Adjust the alignment angles (camber, caster, toe) according to the manufacturer's specifications.
Complete the alignment and remove the equipment.

4. Suspension Component Inspection

Inspect control arms, tie rods, and bushings for any signs of wear or damage.
If any components are damaged, replace them with OEM parts.
Recheck the alignment after replacing any suspension components.
