First secure the piston rod with a 6 mm hexagon wrench and then proceed to remove the nut followed by support plate and cushion then spring bracket before finishing with upper insulator and suspension support and spring bumper and coil spring. Check the shock absorber function by pressing and releasing the rod since abnormal resistance or sounds indicate a replacement is needed.
