Before disassembling the shock, it has to be taken out of the car. Apply a Strut Spring Compressor, teamPSE tool 223-7400 or any other similar tool and use the maker's instructions to begin the process. Make sure the shock rod nut doesn't come off until you've compressed the coil spring and relieved stress on the upper mounting bracket. Write the names of each shock on the bottom parts of their coil springs to indicate where they go. If fitted with a noise abatement cap, remove it and after that, put the shock assembly into the strut spring compressor, hooking the bottom and top shut with the coil spring. Compress the coil spring tightly enough that all tension goes out of the upper mounting bracket and bushings. Avoid powerful and rapid tools to not damage the shock's internal bearings. Install a Snap-On(R) Shock Absorber Socket A139 or similar on the shock rod and, after putting the rod under tension, unthread and remove the nut and washer with a wrench. Grab the shock absorber from beneath the coil spring which will let go of the washer, jounce bumper, dust shield and lower spring isolator. Slip the washer, jounce bumper and dust shield from the shock rod and take off the lower isolator from the shock seat. Take off the bracket, bushings, sleeve and upper spring isolator from the spring. Then remove the bushings, sleeve and upper spring isolator from the upper mounting bracket. When working on the coil spring, back the compressor drive off, move the hooks back and get rid of the coil spring. Evaluate the shock assembly by checking for shaft binding, cracks, deterioration and wear on the shock, jounce bumper, dust shield, upper mounting bracket, bushings, sleeve, spring isolators and coil spring coating.
