The following tools are needed to service and repair the suspension strut: holding fixture (J 3289-20), strut compressor (J 34013-B), damper rod clamp (J 34013-20), alignment rod (J 34013-197), strut rod nut socket (J 42991), strut compressor lower adapter (J 34013-971), and strut compressor upper adapter (J 34013-972) are other parts. Start by stripping off the strut from the vehicle and fitting it into the strut compressor (J 34013-B), fitting the strut compressor lower adapter (J 34013-971), strut compressor upper adapter (J 34013-972), and holding fixture (J 3289-20). Turn the compressor forcing screw until the spring is slightly compressed, and then use a 45 torx socket to hold the strut shaft and remove the strut mount nut with the strut rod nut socket (J 42991). Replace the alignment rod (J 34013-197) to direct the strut shaft in the upper mount while loosening compressor screw and pulling the strut shaft out. For assembly, properly orienting the strut mount and assembling the strut in the strut compressor (J 34013-B) with adapters and the damper rod clamp (J 34013-20). Inset the spring and push it up, replace the upper locking pin. Using the alignment rod (J 34013-197), use to guide the strut shaft turn the compressor screw clockwise until strut shaft threads are visible. The washer and nut applied, damper rod clamp (J 34013-20) removed; tighten strut mount nut to 85 nm (63 ft. Lbs.) with the strut rod nut socket (J 42991) while braking the strut shaft with a 45 torx socket. Lastly, take out the strut from the compressor and place it back into the vehicle.
