Solution

1. Preparation

Gather tools and parts required for the alignment process.
Ensure vehicle is parked on a level surface.
Raise the vehicle using a hydraulic lift or jack stands for easier access to suspension components.

2. Inspect and Replace Worn Components

If worn suspension components are found during the diagnostic step, replace them.
1. Remove damaged components (e.g., tie rods, control arms).
2. Install new components according to the manufacturer's specifications.
3. Torque all fasteners to the specified values using a torque wrench.

3. Perform Wheel Alignment

Setup Alignment Machine:
- Attach the alignment tools to the wheels per the manufacturer's instructions.
Adjust Toe Angle:
- Check the toe angles; adjust by turning the tie rod ends until the specified toe settings are achieved.
Adjust Camber and Caster:
- If necessary, adjust the camber and caster by modifying the strut mounts or using camber/caster bolts.
Recheck Alignment:
- After adjustments, recheck all angles to ensure they are within the specified range.

4. Test Drive the Vehicle

Lower the vehicle and take it for a test drive to confirm that the alignment is corrected and to check for any additional symptoms.
