- Tighten all suspension hardware to the manufacturer’s torque specifications (refer to service manual).

3. Perform Wheel Alignment

Sub-steps:
- Place the vehicle on an alignment rack and attach the alignment sensors.
- Adjust the toe angles to manufacturer specifications (typically within 0.05 degrees).
- Adjust the camber angle as needed (generally should be within 0.5 degrees of specifications).
- Adjust the caster angle as needed (if applicable) to ensure proper handling.
- Recheck all angles after adjustments to confirm they are within specifications.

4. Test Drive and Check Alignment

Sub-steps:
- Remove the vehicle from the alignment rack.
