Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Safety warning: Disconnect the battery if working on electronic wheel sensors.

2. Tire Inspection and Replacement

Inspect tires for visible damage or uneven wear patterns.
If tires are damaged or excessively worn, replace them:
1. Loosen lug nuts using a torque wrench, then lift the vehicle with a jack.
2. Remove the wheels and replace with new tires, ensuring they are the correct size and type.
3. Reattach the wheels and tighten the lug nuts to manufacturer specifications.

3. Wheel Balancing

If tire condition is acceptable, balance the wheels:
1. Remove the wheel from the vehicle.
2. Place the wheel on a wheel balancing machine and check for balance.
3. Add weights as necessary to achieve balance.
4. Reinstall the balanced wheel onto the vehicle.

4. Suspension Inspection and Repair

Inspect the suspension system:
1. Check control arms, bushings, and ball joints for wear or damage.
2. Replace any worn or damaged components following manufacturer guidelines.
3. Use the proper torque specifications for reassembly.

5. Wheel Alignment

Perform wheel alignment:
1. Set the vehicle on an alignment rack.
2. Adjust the camber, caster, and toe angles to manufacturer specifications.
3. Test drive to ensure proper handling and tracking.
