- If damaged, remove the old links and install new ones, ensuring proper torque.
Control Arms and Bushings:
- Check control arms for any visible damage or excessive play.
- If bushings are worn, replace them by removing the control arm and pressing out the old bushings, then press in the new ones.

4. Reassemble and Lower Vehicle

Reattach the wheels and ensure all bolts are tightened to the specified torque.
Carefully lower the vehicle back to the ground.
