Solution

1. Preparation

Tools Required: Jack, jack stands, tire pressure gauge, torque wrench, alignment tool
Ensure the vehicle is parked on a level surface, and the engine is off.

2. Tire Inspection

Sub-steps:
- Check tire pressure using a tire pressure gauge and inflate to the manufacturer's specifications if needed.
- Visually inspect the tires for bulges, cuts, or uneven tread wear.
- If damage is found, replace the tires as necessary.

3. Wheel Balancing

Sub-steps:
- Remove the wheels using a jack and jack stands.
- Take the wheels to a tire shop for professional balancing.
- Reinstall wheels once balancing is completed, ensuring lug nuts are torqued to the manufacturer’s specifications.

4. Wheel Alignment

Sub-steps:
- If vibrations persist, perform a wheel alignment using alignment tools.
- Adjust the toe, camber, and caster angles to match manufacturer specifications.
- Test drive the vehicle to verify the alignment correction.

5. Suspension and Drivetrain Inspection

Sub-steps:
- Visually inspect all suspension components for wear (bushings, shocks, struts).
- Check for excessive play in ball joints and tie rods.
- Inspect the driveshaft and CV joints for signs of wear or damage.
- Replace any worn components as necessary.
