Solution

1. Preparation

Gather tools including a jack, jack stands, tire iron, and alignment tools.
Ensure the vehicle is parked on a flat surface and the engine is off.
Safety Warning: Always engage the parking brake and use wheel chocks when lifting the vehicle.

2. Check and Balance Tires

Loosen the lug nuts on the wheel to be checked.
Lift the vehicle using a jack and secure it on jack stands.
Remove the wheel and take it to a tire balancing machine.
Balance the tire, adding weights as necessary.
Reinstall the wheel, tightening lug nuts to manufacturer specifications (typically 80-100 ft-lbs).

3. Perform Wheel Alignment

Position the vehicle on an alignment rack.
Follow the manufacturer's instructions to adjust camber, caster, and toe settings as needed.
Confirm that alignment settings are within manufacturer's specifications.

4. Inspect and Replace Suspension Components

Visually check all suspension components for wear or damage.
Replace any damaged tie rods, control arms, or bushings as necessary.
Reinstall any components, ensuring all fasteners are torqued to specification.

5. Inspect Brake Rotors

Remove the wheels to access the brake rotors.
Check for warping by measuring rotor thickness at multiple points.
If warped, replace the rotors with new ones that meet OEM specifications.
