Replace Tires (if necessary):
- 1. Loosen the lug nuts using a lug wrench.
- 1. Lift the vehicle using a jack and secure with jack stands.
- 1. Remove the lug nuts and take off the affected tire.
- 1. Install the new tire and hand-tighten the lug nuts.
- 1. Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (typically 80-100 ft-lbs).

3. Wheel Alignment and Balancing

Wheel Alignment:
- 1. Take the vehicle to a professional alignment shop.
- 1. Ensure that the alignment settings are adjusted to manufacturer specifications.
Wheel Balancing:
- 1. If vibrations persist, visit a tire shop to have the wheels balanced.
- 1. Adjust any imbalances as required.

4. Suspension Repair

Inspect and Replace Worn Suspension Components:
- 1. Visually inspect control arms, bushings, and struts for damage.
- 1. Replace any worn or damaged parts using appropriate tools (e.g., socket set, wrenches).
- 1. Torque new components to the manufacturer's specifications.

5. Drivetrain Inspection

Check Driveshaft and CV Joints:
- 1. Inspect the driveshaft for any signs of damage or excessive play.
- 1. Replace any damaged driveshaft or CV joint as needed.
- 1. Reinstall and ensure all fasteners are properly torqued.
