Solution

1. Preparation

Gather tools: Alignment tool, floor jack, jack stands, torque wrench, and a wheel chock.
Ensure the vehicle is parked on a level surface.

2. Raise the Vehicle

Use a floor jack to lift the front of the vehicle.
Secure with jack stands to ensure safety while working.
Place wheel chocks behind the rear wheels.

3. Adjust Wheel Alignment

Toe Adjustment:
- Measure the distance between the front and rear of the front tires.
- Adjust the tie rods by turning them to achieve the manufacturer's specified toe settings (typically 0.1 to 0.2 degrees).
- Recheck measurements to ensure they are within specifications.
Camber Adjustment:
- If camber is out of spec, adjust the upper control arm or strut mounting bolt as needed.
- Use a camber gauge to ensure the angle is within the manufacturer's specifications (usually around 0.5 degrees).
Caster Adjustment:
- If caster is off, adjust the control arm bolts or strut mount as necessary.
- Ensure the caster is within the specified range (typically 6 to 7 degrees).

4. Final Checks

Lower the vehicle and remove jack stands.
Recheck the alignment settings with the alignment tool.
Perform a test drive to verify that the steering wheel is centered and the vehicle tracks straight.
