Solution

1. Preparation

Tools Required: Floor jack, jack stands, torque wrench, tire pressure gauge, wheel balancing machine, alignment tool.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery if working on any electrical components related to the suspension.

2. Tire Inspection and Replacement

Sub-steps:
1. Remove the wheel covers or hubcaps if applicable.
2. Loosen the lug nuts on the affected wheels while the vehicle is still on the ground.
3. Use a floor jack to lift the vehicle and secure it with jack stands.
4. Remove the wheels and inspect for visible damage or uneven wear.
5. Replace any damaged tires with new ones that meet OEM specifications.

3. Wheel Balancing

Sub-steps:
1. Mount the wheels on the wheel balancing machine.
2. Spin the wheels to identify any imbalance.
3. Attach the appropriate weights to correct any imbalances.
4. Reinstall the wheels and torque the lug nuts to the manufacturer’s specifications (typically 100-150 lb-ft depending on the model).

4. Wheel Alignment

Sub-steps:
1. Use an alignment tool to check the camber, caster, and toe angles.
2. Adjust the alignment settings according to the manufacturer's specifications.
3. Test drive the vehicle again to ensure the alignment has resolved the issue.

5. Suspension Inspection and Repair

Sub-steps:
1. Inspect all suspension components, including control arms, struts, and bushings for wear or damage.
2. Replace any worn or damaged components following OEM specifications.
3. Ensure all bolts are torqued to the manufacturer’s specifications.
