Preliminary Procedure: NOTE: Use care when handling the coil springs in order to avoid chipping or scratching the coating. Damage to the coating will result in premature failure of the coil springs. Remove the shock module. Refer to Shock Module Replacement .
1	Nut NOTE: Do not allow the absorber rod to rotate during disassembly/reassembly. Use hand tools to keep the absorber rod from rotating. If air tools are used, and the rod is allowed to rotate, damage to the absorber may occur. NOTE: Refer to Fastener Notice . Tip: Mark the alignment for the shock module assembly prior to disassembly. The marks will aid in alignment during installation. The use of J 45400 Strut Spring Compressor or equivalent, is required before removing the nut. See Special Tools . The spring is compressed when the shock absorber moves freely. Tighten: 42 N.m (31 lb ft)
