- Check for leaks or damage.
- If damaged, unbolt the top and bottom mounts using a socket set.
- Remove the old shocks/struts and replace them with new units.
Check Sway Bar Links:
- Inspect for wear or breakage.
- If worn, remove the bolts using a torque wrench and replace with new sway bar links.
Control Arm Bushings:
- Inspect for cracking or deterioration.
- If necessary, support the control arm and remove the bolts. Replace bushings with new ones.

4. Reassemble and Lower the Vehicle

Reattach all components securely.
Ensure all bolts are torqued to manufacturer's specifications.
Carefully lower the vehicle back to the ground.
