Solution

1. Tire Pressure Adjustment

Check the tire pressure on all four tires using a tire pressure gauge.
Inflate or deflate tires as necessary to match the specifications found in the owner’s manual or on the driver’s door jamb.

2. Tire Rotation and Replacement

If uneven tire wear is detected, rotate the tires according to the manufacturer's recommended pattern.
Replace any severely worn or damaged tires to ensure even traction and handling.

3. Wheel Alignment

Preparation:
- Gather alignment tools, including an alignment rack and laser alignment tools.
- Ensure the vehicle is on a level surface and the steering wheel is centered.
Adjust Alignment:
- Adjust the camber, caster, and toe angles according to the specifications provided by the manufacturer.
- Tighten all adjustment bolts to the specified torque values to secure the settings.

4. Suspension Component Inspection and Repair

Inspect all suspension components for wear or damage, focusing on control arms, ball joints, and bushings.
Replace any damaged or worn components with OEM parts, following proper installation procedures.
Ensure all bolts are torqued to the manufacturer’s specifications.
