Lift the vehicle: Use a jack to raise the vehicle and support it on jack stands.
Check components: Visually inspect suspension parts for cracks or excessive wear, including control arms, struts, and tie rods.
Replace any damaged components: If damage is found, replace parts as necessary.

4. Wheel Alignment

Align wheels: After addressing all previous issues, take the vehicle to an alignment shop to ensure proper alignment settings.
Use alignment equipment: Follow the manufacturer's specifications for alignment angles.

5. Test Drive
