Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.
Gather necessary safety equipment (gloves, safety glasses).

2. Tire Rotation and Balancing

Sub-steps:
1. Remove the wheel covers or hubcaps if applicable.
2. Loosen lug nuts slightly while the vehicle is on the ground.
3. Lift the vehicle with a jack and secure it with jack stands.
4. Remove the wheels completely.
5. Take the tires to a tire balancing machine, balance them according to specifications, and re-install them on the vehicle.
6. Torque the lug nuts to the manufacturer’s specifications (usually 80-100 ft-lbs).

3. Alignment Adjustment

Sub-steps:
1. Set the vehicle on an alignment rack.
2. Check for toe, camber, and caster angles using the alignment machine.
3. Adjust alignment settings as necessary to meet the manufacturer’s specifications.
4. Recheck after adjustments to ensure alignment is within tolerance.

4. Suspension Inspection and Repair

Sub-steps:
1. Inspect the suspension for worn components such as bushings, ball joints, and struts.
2. Replace any damaged or worn components with OEM or high-quality aftermarket parts.
3. Reassemble any components that were disassembled for the inspection.
