Coil Spring, Front

The service and repair of the front shock absorber with coil spring begins with front wiper arm head cap removal followed by disconnecting both left and right front wiper arms and removing the hood to cowl top seal and the cowl top ventilator louvers. The service starts with disconnecting the wiper hose and wire harness before removing 8 bolts from the cowl top panel outer and windshield wiper link assembly. The shock absorber repair begins by removing the front wheel as well as the flexible hose by unscrewing its bolt then releasing the ABS speed sensor wire harness clamp from its bracket position. Detach the 2 nuts and 2 bolts securing the steering knuckle before removing the front shock absorber together with its coil spring. The shock absorber requires unfastening its 3 nuts and the No. 2 suspension support. Secure the front shock absorber with coil spring in a vise through two nuts while employing a bolt to compress the coil spring using Special Service Tool: 09727-30021 (09727-00010, 09727-00021, 09727-00031). Use this tool instead of an impact wrench because it prevents equipment damage. Begin by using a screwdriver with 2 nuts to remove the front suspension support dust cover along with the front support to front shock absorber left-hand nut followed by extraction of the front suspension support left-hand subassembly and dust seal with coil spring seat upper, coil spring insulator upper and coil spring and spring bumper. Inspects the front shock absorber assembly by testing the shock absorber rod for irregular resistance or noises despite compression and extension and needs direct replacement. Reassemble by first putting on the front shock absorber assembly followed by the spring bumper and coil spring and using the special service tool to compress the coil spring to let its lower end fit into the space of the spring lower seat. Position the front coil spring insulator upper first while making sure its mark points toward the exterior followed by the front coil spring seat upper which reveals its marked side to the outside. Assemble the left-hand front suspension dust seal subcomponent after installing its center nut using new hardware while torquing to 33 Nm (340 kgf-cm, 25 ft. lbs.) yet maintain care when avoiding contact with the suspension support bolts. Proceed by installing the dust cover on the suspension support after applying MP grease to it and removing the special service tool. The installation process requires front shock absorber assembly attachment with proper positioning of No. 2 suspension support while securing the shock absorber using 3 nuts tightened to 39 Nm (400 kgf-cm, 29 ft. lbs.) to connect the steering knuckle area and completing the installation with 2 bolts and a nut torqued to 132 Nm (1,350 kgf-cm, 97 ft. lbs.). Follow these installation steps: first torque the flexible hose to 29 Nm (300 kgf-cm) and then install the front wheel to 103 Nm (1,050 kgf-cm) while finishing with the cowl top panel outer bolted by 8 fasteners torqued to 5.0 Nm (51 kgf-cm). Next reconnect the hose and wire harness for the wiper. The windshield wiper link assembly along with both cowl top ventilator louvers and the hood to cowl top seal need installation after positioning the front wiper arms so you can inspect and perform adjustments to the front wheel alignment. When disposing of the shock absorber rods should be fully stretched before drilling a hole through the cylinder while using protective safety gear because of metal part hazards.

Remove the nut to disconnect the rear shock absorber assembly LH, and repeat the same procedures for the RH side.

Reinstall the flexible hose, torquing it to 29 Nm, then the front wheel with a torque of 103 Nm.

Bleed the brake line, install the rear wheel with a torque of 103 Nm (1,050 kgf-cm, 76 ft. lbs.), inspect the rear wheel alignment, and check the ABS speed sensor signal.
