Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Place wheel chocks behind the rear wheels for safety.

2. Tire Rotation

Remove all tires using a lug wrench.
Rotate tires according to the recommended pattern (e.g., front to back, side to side).
Inspect tires for damage or irregular wear and replace if necessary.
Reinstall tires and hand-tighten the lug nuts.

3. Wheel Alignment

Set up the vehicle on an alignment rack.
Perform a preliminary alignment check and note the current specifications.
Adjust the front camber, caster, and toe angles to meet manufacturer specifications.
Adjust the rear camber and toe angles if applicable.
Confirm all adjustments are within the acceptable range.

4. Suspension Inspection/Repair

Inspect all suspension components for any signs of wear or damage.
Replace any worn components (e.g., control arms, bushings, struts).
Ensure all hardware is torqued to manufacturer specifications.

5. Final Steps

Lower the vehicle and perform a final torque check on the lug nuts using a torque wrench.
Remove wheel chocks and safely drive the vehicle to ensure proper handling.
