The rear strut assembly can only be disassembled after it has been removed from the vehicle. To compress the coil spring, apply a strut spring compressor, use PSE tool W-7200 or an alternative tool as shown in the manufacturer's instructions. If handling both struts together, label the coil spring and strut bar on the driver's side and the passenger's side. Install the strut assembly below the compressor, attaching the lower hook to the coil, the upper hook to the upper mount and make sure the strut clevis bracket points inward. Put on a clamp at the base of the coil spring to make sure the strut does not move after you remove the strut shaft nut. Before you unscrew the strut shaft nut, first compress the coil spring to let off the tension in the upper mount and bearing. After the spring is compressed, put Strut Nut Socket, Special Tool 6864, on the nut secured to the strut shaft and with the strut shaft held, take out the nut. With the upper mount taken off, remove the clamp and carefully pull the strut through the coil spring. After taking off the dust shield and jounce bumper from the strut shaft, lose the lower spring isolator on the lower spring seat of the strut. Should the coil spring need attention, stop the drive of the compressor, press back the hooks and lift out the broken part of the coil spring. Inspect the strut assembly by looking for problems such as shaft binding, cracks, wear on the jounce bumper, damage to the upper mount and its retaining studs, rips in the dust shield, aging in the isolators and any harm to the coil spring's protective coating, repairing and replacing parts as needed.
