• Q: How to service and repair the front shock absorber with coil spring on 2001 Toyota 4Runner?

  A: The first step to repair the front shock absorber with coil spring begins with removing the front wheel and tightening it to 110 Nm (1,150 kgf-cm, 83 ft. lbs.). The shock absorber's connection to the lower suspension arm needs both bolt loosening and lower nut and washer removal with 135 Nm torque (1,400 kgf-cm, 101 ft. lbs.). After this disconnect both components so the suspension arm can be lowered. The procedure for removing the shock absorber with coil spring includes disassembly of three nuts which require a torque setting at 64 Nm (650 kgf-cm, 47 ft. lbs.). Special Service Tools 09727-00060 and 09727-30021 should be used to compress the coil spring until adequate clearance exists on both sides while maintaining proper arm positioning and avoiding tool damage through avoiding spring over-compression. Unfasten the two retainers along with the suspension support center nut and coil spring and cushion from the assembly. Check your shock absorber for any abnormal resistance or sounds while compressing and extending its rod. Replace the unit in case you detect any issues. To discard the shock absorber completely extend its rod then drill a hole into the cylinder panel with caution toward escaping debris. The replacement procedure requires the bushing removal by tools Special Service Tool: 09506-35010 and 09632-36010 through a press and new bushing installation without grease or oil. Reassembling requires the same special service tools to compress the coil spring then place the coil spring onto the shock absorber with the lower end set to enter the spring seat gap properly. After inserting the suspension support and cushion onto the rod the technician should first tighten the newly installed suspension center nut then adjust the suspension support toward the shock absorber lower bushing before releasing the special service tools to confirm the suspension support alignment before torquing the suspension center nut to 25 Nm (250 kgf-cm, 18 ft lbs). The last step of installation follows the exact reverse procedure of disassembly.
