Solution

1. Preparation

Gather necessary tools and parts.

Wear safety glasses and gloves.

2. Tire Inspection

Remove the wheel cover or hubcap if necessary.
Inspect each tire for uneven wear patterns, bulges, or foreign objects.
Replace any damaged tires if necessary.

3. Tire Rotation

Rotate tires to ensure even tread wear if uneven wear is identified.
- Front tires should be moved to the rear and vice versa.
Tighten lug nuts to the manufacturer’s specified torque value (usually around 80-100 ft-lbs).

4. Wheel Alignment

Take the vehicle to a certified alignment shop.
Perform a four-wheel alignment following the manufacturer’s specifications.
Adjust toe, camber, and caster angles as necessary.

5. Suspension Inspection and Repair

Inspect suspension components such as tie rods, ball joints, and control arms.
Replace any worn or damaged components with OEM or quality aftermarket parts.
Recheck the alignment after replacing suspension parts.
