Coil Spring, Rear

Before attaching the rear shock absorber and coil spring begin by squeezing the coil spring using Special Service Tools: 09727-30021 and 09727-00010. Using an impact wrench is forbidden because it can damage the equipment. Cable the coil spring onto the shock absorber by placing its lower section into the spring lower seat gap. Construct the installation by firstly hanging the No. 1 spring bumper LH and suspension support LH then inserting the coil spring insulator upper LH into the spring front bracket LH. Position the spring front bracket on the left-hand side with the coil spring insulator upper on both sides as shown in the illustration and make sure the right-hand side matches the left-hand side for symmetry. Next install the suspension support LH along with No. 1 shock absorber cushion washer followed by temporarily tightening a new center nut while using the Special Service Tool but removing it in between. The 6 mm hexagon wrench should be used to stabilize the piston rod as technicians tighten the nut to a correct torque value of 56 Nm (571 kgf-cm, 41 ft-lbf). The last step involves installing the cap onto the shock absorber.

The first step for disassembling a rear shock absorber with coil spring requires removal of the rear shock absorber cap. Compress the coil spring with Specific Service Tool: 09727-30021 and 09727-00010 while avoiding impact wrenches since they can harm the tool. The first step is to hold the piston rod with a 6 mm hexagon wrench and unscrew the nut. The disassembly requires removal of the No. 1 shock absorber cushion washer and subsequent components including the suspension support LH, spring front bracket LH, No. 1 shock absorber cushion and No. 1 spring bumper LH, coil spring insulator upper LH. Finally, remove the coil spring.

First, take off the front suspension support dust cover, then loosen the lock nut without removing it, and remove the two nuts on the lower side while keeping the bolts inserted.

Take off the front wiper arm head cap, followed by the front wiper arm and blade assembly on both the left-hand and right-hand sides.

Avoid the use of an impact wrench to prevent damage to the tool.

Support the front No. 1 suspension lower arm LH with a jack and remove the nut.
