• Q: How to overhaul the front shock absorber with coil spring on 2005 Scion xA?

  A: Start the coil spring front shock absorber overhaul by disassembling the front wiper arm head cap, both wiper arms, hood to cowl top seal and cowl top ventilator louvers on both sides before removing the windshield wiper link assembly and cowl top panel outer while disconnecting the hose and wire harness. Proceed to remove the front wheel then detach the flexible hose by unthreading its bolt and ABS speed sensor wire harness clamp which secures it to the shock absorber bracket. The front shock absorber with coil spring requires detachment from the steering knuckle before you can remove it through the three nuts followed by removing suspension support No.2. Position the front shock absorber with coil spring inside a vise before you install its bracket nuts and bolt while compressing the coil spring through Special Service Tool: 09727-30021 (09727-00010, 09727-00021, 09727-00031). Avoid utilizing an impact wrench to prevent damage. The process starts by removing two nuts from the front suspension support dust cover and the front support to front shock absorber left-hand nut using a screwdriver and two nuts followed by removing both the front suspension support sub-assembly and dust seal. The procedure involves uninstalling the front coil spring seat upper together with the coil spring insulator upper and coil spring and spring bumper. Test the shock absorber for standard operating conditions and make a replacement if abnormal resistance or sound occurs. The installation process requires placement of shock absorber assembly and front spring bumper along with coil spring into position while using the special tool to compress the coil spring until its lower end reaches the spring lower seat gap. First insert the front coil spring insulator upper that displays "a" mark outward before placing the front coil spring seat upper bearing "OUT" mark away from the assembly's center. Finish with installation of the front suspension support dust seal. Reinstall the front suspension support sub-assembly by securing its attachment to the front shock absorber left-hand nut that requires 33 Nm (340 kgf-cm, 25 ft. lbs.) of torque force and avoiding damage to the suspension support stud bolts. The special tool must be cleaned off before applying MP grease to the suspension support after its installation of the dust cover. To complete the installation the front shock absorber with coil spring must be fastened to the steering knuckle before torqueing its bolts and nuts to proper specifications while adding the flexible hose and front wheel components together with cowl top panel outer and windshield wiper link assembly followed by the cowl top ventilator louvers and hood to cowl top seal and both front wiper arms and performing inspection for front wheel alignment adjustment. Drilling a hole in the cylinder for gas discharge requires proper safety equipment because metal shards might appear during the process. Operators must extend the shock absorber rod to the maximum position before performing this step.
