Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and is secure.
Disconnect the negative battery terminal to prevent electrical issues.

2. Tire Inspection

Inspect each tire for bulges, cuts, or foreign objects.
Measure tire pressure using a tire gauge and inflate to the manufacturer’s recommended PSI.
If any tires show uneven wear, consider rotating them or replacing them if necessary.

3. Wheel Alignment and Balance

Use a wheel alignment tool to check and adjust the alignment settings according to the manufacturer's specifications.
If balance issues are suspected, take the vehicle to a tire shop to balance all four wheels.

4. Drivetrain Inspection

Raise the vehicle on jack stands and inspect the driveshaft and CV joints.
Look for any cracks, tears, or excessive play in the joints; replace if necessary.

5. Suspension Check

Inspect suspension components (shocks, struts, control arms) for wear or damage.
Tighten any loose bolts or replace worn-out parts as needed.

6. Reconnect Battery and Test Drive

Reconnect the negative battery terminal.
Take the vehicle for a test drive to confirm that the vibrations have been resolved.
