Solution

1. Tire Inspection

1.1. Remove Wheels
- Use a jack to lift the vehicle and secure with jack stands.
- Remove the lug nuts using a socket set and take off the wheels.
1.2. Inspect Tires
- Check for uneven wear patterns or bulges on the tire sidewalls.
- Measure tire pressure and adjust to the manufacturer’s specifications.

2. Wheel Balancing

2.1. Balance Check
- Mount each wheel onto a balancing machine.
- Adjust weights to balance the wheels as required.

3. Suspension Inspection

3.1. Visual Inspection
- Check for any visible damage or wear on control arms, bushings, and struts.
3.2. Component Testing
- Use a pry bar to test for play in suspension components.
- Replace any worn components as necessary.

4. Driveshaft and U-Joint Inspection

4.1. Inspect Driveshaft
- Visually inspect the driveshaft for any signs of bending or damage.
4.2. Check U-Joints
- Manually check for excessive play in the U-joints; replace if necessary.

5. Reassemble and Test Drive

5.1. Reinstall Wheels
- Torque lug nuts to the manufacturer's specifications (typically around 100-120 ft-lbs).
5.2. Lower Vehicle
- Remove jack stands and lower the vehicle.
5.3. Test Drive
- Take the vehicle for a test drive to confirm the vibration has been resolved.
