Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Tire Rotation

Sub-steps:
1. Loosen the lug nuts on all four wheels slightly while the vehicle is on the ground.
2. Use a jack to lift the vehicle and secure it with jack stands.
3. Remove the wheels and check for uneven wear patterns.
4. Rotate the tires according to the vehicle’s specified rotation pattern (front-to-back or crisscross).
5. Reinstall the wheels and hand-tighten the lug nuts.

3. Wheel Alignment Adjustment

Sub-steps:
1. Take the vehicle to a professional alignment shop or use an alignment machine.
2. Adjust the camber, toe, and caster angles according to the manufacturer's specifications.
3. Perform a test drive to ensure the vehicle tracks straight.

4. Suspension Component Inspection and Repair

Sub-steps:
1. Inspect control arms, bushings, struts, and shocks for wear.
2. Replace any damaged components as necessary (e.g., control arms, bushings).
3. Recheck alignment after any suspension component replacements.
