INSTALLATION
HINT:
- Use the same procedure for the LH side and RH side.
- The following procedure listed is for the LH side.

1. INSTALL FRONT SHOCK ABSORBER





(a) Install the front lower coil spring insulator to the front shock absorber so that both recessed parts are aligned.





(b) Using SST, compress the front coil spring.
SST: 09727-30021
09727-00010
09727-00021
09727-00031
NOTE:
Do not use an impact wrench. It will damage SST.





(c) Install the front coil spring so that the end comes to the stepped portion of the lower spring seat.





(d) Install the front spring bumper on the front suspension support assembly.
(e) Align the bolt of the front suspension support assembly with the cutout of the front upper coil spring insulator, and install the front upper coil spring insulator on the front suspension support assembly.





(f) Match the shape of the piston rod end to the shape of the front suspension support assembly to install the front shock absorber.
(g) Install the front actuator support bracket.
(h) Temporarily tighten a new lock nut to the front shock absorber.





(i) Adjust the front suspension support assembly so that the bolts come to the positions shown in the illustration, and remove the SST from the front coil spring.
- Do not use an impact wrench. It will damage the SST.
- Make sure of the direction of the front suspension support assembly when removing the SST.

2. TEMPORARILY TIGHTEN FRONT SHOCK ABSORBER WITH COIL SPRING





(a) Install the front shock absorber with front coil spring and front No. 3 spring support reinforcement on the vehicle by tightening the 3 nuts on the suspension support side.
Torque: 67 Nm (683 kgf-cm, 49 ft-lbf)





(b) Insert the bolt from the rear of the vehicle, and install the front shock absorber lower side on the front lower suspension arm.
(c) Temporarily tighten the nut while holding the bolt.
HINT: Fully tighten the nut after stabilizing the suspension.





(d) Tighten a new lock nut.
Torque: 28 Nm (286 kgf-cm, 21 ft-lbf)
3. INSTALL FRONT UPPER SUSPENSION ARM ASSEMBLY
