Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface, and engage the parking brake.

2. Tire Inspection and Replacement (if needed)

Sub-steps:
- Remove the wheels using a socket set.
- Inspect each tire for wear, and if any tires are damaged or excessively worn, replace them with new tires.
- Ensure that the new tires are properly rated for the vehicle.

3. Wheel Balancing

Sub-steps:
- Mount the tires on a wheel balancing machine.
- Spin the tires to identify any imbalances, and add wheel weights as necessary to achieve balance.
- Reinstall the balanced wheels on the vehicle and torque lug nuts to the manufacturer’s specified torque (usually around 80-100 ft-lbs).

4. Wheel Alignment

Sub-steps:
- Place the vehicle on an alignment rack.
- Adjust the alignment to the manufacturer's specifications, focusing on toe, camber, and caster angles.
- Test drive the vehicle post-alignment to ensure proper handling.

5. Suspension Inspection and Repair (if needed)

Sub-steps:
- Inspect all suspension components for excessive wear, focusing on bushings and joints.
- Replace any worn suspension parts with OEM or high-quality aftermarket parts.
- Reassemble any components removed during inspection.
