Solution

1. Tire Balancing

Lift the vehicle using a jack and secure it with jack stands.
Remove the wheels using a lug wrench.
Place each wheel on a wheel balancer and adjust weights as necessary until balanced.
Reinstall the wheels and torque the lug nuts to the manufacturer’s specifications (usually 80-100 ft-lbs).

2. Tire Replacement (if necessary)

If tires are damaged or excessively worn, replace them with new ones that meet the manufacturer’s specifications.
Ensure that the new tires are properly inflated according to the placard on the driver's door jamb.

3. Wheel Alignment

Use an alignment machine to check and adjust the wheel alignment.
Adjust the camber, caster, and toe settings to factory specifications.

4. Suspension Inspection and Repair

Visually inspect all suspension components for damage or wear.
Replace any worn or damaged parts (such as shocks or control arms) with OEM or high-quality aftermarket parts.
Reassemble any components that were removed or adjusted.
