- Remove the wheels from the vehicle using a socket set.
- Mount the wheels on a tire balancing machine and adjust weights as necessary to balance.

2. Suspension Component Check

Inspect Suspension:
- Lift the vehicle using a jack and secure it with jack stands.
- Check all suspension components (shocks, struts, control arms) for any signs of damage or excessive wear.
- Replace any damaged components with OEM parts.

3. Driveshaft Inspection

Examine Driveshaft:
- Check the driveshaft for any signs of bending or damage.
- Inspect U-joints for play or binding. Replace if necessary.
Reinstall Driveshaft:
- Reinstall the driveshaft, ensuring proper alignment and secure fastening with the specified torque.

4. Wheel Alignment

Perform Alignment:
- After any tire or suspension repairs, use an alignment machine to ensure the wheels are properly aligned.
- Adjust camber, caster, and toe to manufacturer specifications.
