Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secured with wheel chocks.
Disconnect the negative battery terminal for safety (if applicable).

2. Inspect and Adjust Tire Pressure

Use a tire pressure gauge to measure the pressure in all four tires.
Inflate or deflate tires to the manufacturer's recommended pressure levels (found in the owner's manual or on a sticker inside the driver's door).

3. Wheel Balancing

Remove the wheels using a socket set.
Mount each wheel on a balancing machine to identify imbalances.
Add balancing weights as needed to achieve proper balance.
Reinstall the wheels, tightening lug nuts to the manufacturer's torque specification (typically 80-100 ft-lbs).

4. Suspension Inspection

Visually inspect all suspension components for cracks, wear, or looseness.
Replace any worn or damaged components such as control arms, bushings, or tie rods.
Ensure all bolts are tightened to the specified torque.

5. Wheel Alignment

Use a wheel alignment machine to check the alignment settings.
Adjust the camber, caster, and toe angles to meet manufacturer specifications.
Test drive the vehicle again to ensure vibrations are resolved.
