Solution

1. Preparation

Gather the necessary tools and parts.
Ensure the car is parked on a flat surface and securely lift the vehicle using a jack and jack stands.

2. Tire Pressure Adjustment

Use a tire pressure gauge to check the inflation levels of all tires.
Inflate or deflate tires to the recommended pressure found on the driver’s side door jamb.

3. Tire Inspection and Rotation

Remove the front tires using a socket set.
Inspect for uneven wear patterns; if significant wear is found, consider replacing the tires.
Rotate tires if necessary (e.g., front to rear) according to the manufacturer's rotation pattern.

4. Wheel Alignment

Set up the vehicle on a four-wheel alignment machine.
Adjust the alignment angles (camber, caster, toe) to meet the manufacturer’s specifications.
Tighten all adjustment bolts to the specified torque values.

5. Suspension Inspection and Repair

Inspect suspension components for damage or wear.
Replace any worn or damaged parts (e.g., control arms, bushings).
Re-check alignment after any suspension component replacement.
