Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Visually inspect suspension components for wear or damage; replace any worn parts as necessary.
3. Check for proper mounting and tightness of all suspension bolts using a torque wrench.

4. Wheel Alignment

Sub-steps:
1. Place the vehicle on an alignment rack.
2. Adjust the alignment settings to the manufacturer’s specifications.
3. Confirm all angles (camber, caster, toe) are within acceptable ranges.

5. Rotate Tires

Sub-steps:
1. Remove tires from the vehicle.
2. Rotate the tires according to the recommended pattern (e.g., front-to-back or side-to-side).
3. Reinstall the tires and torque them to the manufacturer’s specifications.
