Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Tools required: Alignment machine, jack and jack stands, torque wrench, and basic hand tools.

2. Adjust Toe Angle

Raise the vehicle using a jack and secure it with jack stands.
Remove the front wheels, if necessary, to access tie rod ends.
Loosen the lock nuts on the tie rods.
Adjust the tie rods to achieve the manufacturer's specified toe angle using the alignment machine.
Tighten the lock nuts to the recommended torque specifications (typically 50-60 ft-lbs).

3. Adjust Camber and Caster

If the alignment machine indicates camber or caster is out of specification, adjust the camber bolts located at the upper control arm.
Loosen the bolts and pivot the control arm to achieve the desired angle.
Re-tighten bolts to manufacturer specifications (typically around 60-70 ft-lbs).

4. Recheck Alignment

After making adjustments, re-check the alignment settings using the alignment machine.
Ensure all angles (toe, camber, and caster) are within manufacturer specifications.

5. Final Assembly

Reinstall the front wheels and lower the vehicle.
Double-check the lug nut torque (typically 140-160 ft-lbs).
Perform a test drive to ensure the vehicle drives straight and the steering wheel is centered.
