Solution

1. Tire Inspection

Inspect all tires for proper air pressure; adjust to manufacturer specifications.
Look for any bulges, cracks, or foreign objects in the tread.
Replace any damaged tires as needed.

2. Wheel Balancing

Remove the wheels from the vehicle using a socket set.
Mount the wheels on a wheel balancer to check for imbalance.
Add wheel weights as necessary to achieve balance.
Reinstall the wheels and torque the lug nuts to the manufacturer's specifications (typically around 80-100 lb-ft).

3. Alignment Adjustment

Use an alignment machine to check the alignment angles (camber, caster, toe).
Adjust the alignment settings to bring them within manufacturer specifications.
Test drive the vehicle afterward to ensure proper handling.

4. Suspension Component Inspection and Replacement

Inspect all suspension components for wear, including control arms, ball joints, and bushings.
Replace any worn or damaged components with OEM or quality aftermarket parts.
Reassemble and torque all fasteners to specification.
