Solution

1. Preparation

Gather tools and parts for the repair.
Park the vehicle on a flat surface and engage the parking brake.
Ensure the engine is off and the keys are removed from the ignition.

2. Tire Inspection and Replacement

Sub-steps:
- Remove the wheel covers or hubcaps if applicable.
- Loosen the lug nuts using a socket set before lifting the vehicle.
- Use a jack to raise the car and secure it with jack stands.
- Remove the wheels and inspect tires for uneven wear, bulges, or foreign objects.
- Replace any damaged tires with new ones, ensuring they match the specifications of the vehicle.

3. Wheel Balancing

Sub-steps:
- Mount the tires on a wheel balancing machine.
- Adjust weights on the rim according to the machine’s readings to achieve balance.
- Reinstall the balanced wheels back onto the vehicle, tightening lug nuts to the manufacturer's torque specifications.

4. Suspension Inspection and Repair

Sub-steps:
- Inspect shocks and struts for leaks or physical damage.
- Replace worn or damaged suspension components using appropriate tools (e.g., socket set, torque wrench).
- Ensure bushings are intact and not cracked or worn.

5. Wheel Alignment

Sub-steps:
- Take the vehicle to a professional alignment shop or use an alignment tool.
- Adjust the toe, camber, and caster angles according to OEM specifications.
- Verify alignment settings and perform a test drive to confirm the fix.
