Shock Absorbers
- Remove the bolts securing the shock absorber to the lower control arm and upper mount.
- Replace the shock absorber, ensuring it is properly seated.
- Torque bolts to manufacturer specifications (typically around 50-60 ft-lbs).
Strut Mounts
- Remove the strut assembly from the vehicle.
- Replace the strut mount with a new one, ensuring proper alignment.
- Reinstall the strut assembly, torque strut nuts to manufacturer specifications.

4. Reassemble and Lower the Vehicle

Reinstall any removed components and ensure all bolts are torqued to specifications.
Carefully lower the vehicle back to the ground.

5. Final Check

Recheck all components and ensure nothing is loose or improperly installed.
