You start by adding the recessed part of the rear lower coil spring insulator to the rear shock absorber assembly unit. After that, install the rear No. 1 spring bumper to the shock absorber assembly. Afterward you should install the rear No. 1 spring bumper to the assembly. After temporary compression of the coil spring with Special Service Tools 09727-30021, 09727-00010, 09727-00021, and 09727-00031 use the tools to install the spring onto the shock absorber assembly. Avoid using an impact wrench for tool safety. The process requires you to position the cutout on the protrusion of the suspension assembly while also inserting the rear support with shock absorber collar and attaching the rear support to rear shock absorber nut. Place the rear coil spring with its end correctly positioned in the insulator's depression while keeping the stud bolt should be angled at 3.5 degrees outward within a range of plus or minus 5 degrees. When installing the rear shock absorber along with coil spring for both 2WD and 4WD vehicles, first apply torque of 58 Nm to three nuts and then tighten two bolts and two nuts to 290 Nm while simultaneously ensuring the bolts maintain their position during nut installation. Lastly, fully tighten the rear support to rear shock absorber nut with 55 Nm torque. Secure the rear No. 1 suspension support cover after adding a disconnected rear stabilizer link assembly onto the shock absorber with coil spring through a tightened nut (torque to 39 Nm) while using a hexagon wrench if the ball joint becomes difficult to turn. The installation process for rear speed sensor wire requires a bolt that needs to be fastened with 5.0 Nm torque for both 2WD and 4WD applications. The rear flexible hose installation requires a bolt on the shock absorber with 19 Nm torque setting and must avoid hose twisting for both car types. To complete the task you should first install deck side trim and deck side trim covers before torquing the rear wheel to 103 Nm while checking and aligning the rear wheel.
