  Q: How to service and repair the front shock absorber with coil springs on Scion xA?

  A:

  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.
• Coil Spring, Rear

  Q: How to replace the rear left coil springs on Scion xA?

  A:

  The replacement procedure for the rear left coil spring begins by taking off the rear wheel followed by disconnecting the skid control sensor connector before removing the bolt to detach the skid control sensor wire from the axle beam. Special Service Tool: 09023-00101 allows you to separate rear brake tube No.4 before removing its clip which must be disposed after use. The same sequence should be followed for disassembling rear brake tube No.3. Follow the same method to detach Parking Brake Cable assembly No.3 from the axle beam by removing its nut. Then use these procedures for parking brake cable assembly No.2 on the right-hand side. Mildly loosen the two bolts which anchor the rear axle beam assembly but do not detach them. Two jacks support the rear axle beam at both sides before technicians remove the nut followed by the spacer which separate the rear left Shock Absorber assembly. Perform the identical shock absorber assembly removal method for the rear right side. Safely lower the jacks to remove both the coil spring along with insulator upper LH and insulator lower LH from the rear left position. Start by installing the insulator upper LH onto the coil spring end component LH as its gap aligns with the coil spring LH end. Then add the insulator lower LH and the coil spring to the rear axle beam with the paint mark beneath the vehicle. The installer can secure the rear left shock absorber assembly to the rear axle beam as jack height increases before continuing with the rear right side operations. Follow the same procedures for parking brake cable assembly No.3 by connecting it with the nut tightened to 5.4 Nm (55 kgf-cm, 48 inch lbs.) and then proceed with No.2 on the right side. The process calls for using Special Service Tool: 09023-00101 to create a 15 Nm (155 kgf-cm, 11 ft. lbs.) torque on rear brake tube No.4 until the clip is secured. Repeat for rear brake tube No.3. Fasten the skid control sensor wire onto its mounting bolt before torquing to 8.0 Nm (82 kgf-cm, 71 inch lbs.). After that, restore the skid control sensor connector. Secure the rear axle beam assembly bolts completely for shock absorber stability before using a jack to support the axle beam and loading its compartment with 90 kg (198 lb.) then torque bolts to 82 Nm (836 kgf-cm, 60 ft. lbs.). Follow the same procedure when tightening the rear right shock absorber assembly nut to 49 Nm (500 kgf-cm, 36 ft. lbs.). The last steps involve bleeding the brake line while installing the rear wheel under 103 Nm (1,050 kgf-cm, 76 ft. lbs.) torque before inspecting the rear wheel alignment and checking the ABS speed sensor signal.
