Solution

1. Tire Inspection

Check each tire for proper inflation and tread wear.
Rotate the tires if uneven wear is found.
Replace any tires that are damaged or excessively worn.

2. Wheel Balancing

Remove the wheel and tire assembly from the vehicle.
Mount the wheel on a balancing machine.
Add weights to balance the wheel as needed; ensure the wheel is evenly balanced.
Reinstall the wheel onto the vehicle, tightening lug nuts to the manufacturer's torque specifications.

3. Wheel Alignment

Use a wheel alignment machine to check the alignment angles (camber, caster, toe).
Adjust alignment settings according to manufacturer specifications.
Test drive the vehicle to confirm proper alignment.

4. Suspension Inspection

Raise the vehicle and support it securely on jack stands.
Inspect suspension components for play or damage; replace worn components as necessary.
Lubricate any moving parts as recommended by the manufacturer.

5. Drivetrain Examination

Inspect the driveshaft for any signs of damage or misalignment.
Check CV joints for wear; replace any damaged parts.
Ensure all bolts and fasteners are tightened to the specified torque.
