Solution

1. Preparation

Tools Required: Alignment rack, torque wrench, jack stands, floor jack, impact wrench, and a digital protractor (if needed).
Raise the vehicle using a floor jack and secure it with jack stands.

2. Adjust Front Toe

Loosen the tie rod end lock nuts using an impact wrench.
Adjust the tie rod length by turning it until the toe angle is within specifications (typically 0.05° to 0.15°).
Re-tighten the lock nuts to the manufacturer’s torque specification (usually around 35-45 ft-lbs).

3. Adjust Camber

Check the camber angle using an alignment machine.
If adjustment is needed, locate the camber adjustment bolts on the strut assembly.
Loosen the bolts and adjust the camber to the specified range (usually around -0.5° to -1.0°).
Re-tighten the bolts to the manufacturer’s torque specification.

4. Adjust Caster (if applicable)

Check the caster angle as it may not be adjustable, depending on the vehicle's design.
If adjustments are required, it may involve repositioning the control arm or strut mount. Refer to a service manual for specific instructions.

5. Final Checks

After adjustments, re-check all alignment angles (toe, camber, caster).
Ensure all bolts are tightened to specification.
Lower the vehicle and remove jack stands.
