Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery for safety if working on suspension components.

2. Tire Rotation

Lift the vehicle using a jack and secure with jack stands.
Remove all four tires using a socket set.
Rotate tires according to the manufacturer’s recommended pattern.
Reinstall tires and torque lug nuts to specification (typically 100-120 ft-lbs).

3. Wheel Alignment

Use alignment equipment to measure angles.
Adjust camber, caster, and toe settings as necessary to bring them within manufacturer specifications.
Tighten any adjustment bolts to the specified torque values.

4. Suspension Inspection and Repair

Inspect struts, shocks, and control arms for wear.
Replace worn components with OEM parts.
Ensure all connections are tightened to specification.

5. Final Check

Recheck tire pressure after completing the repairs.
Reinstall any components removed during the process.
Lower the vehicle and reconnect the battery if disconnected.
