• Q: How to overhaul the front shock absorber with coil spring on 2004 Scion xA?

  A: A complete front shock absorber and coil spring replacement starts by taking out the front wiper arm head cap followed by both front wiper arms and the hood to cowl top seal and the cowl top ventilator louvers from each side. You must then remove the windshield wiper link assembly before accessing the cowl top panel outer when the hose and wire harness are disconnected. First remove the front wheel from the vehicle before disconnecting the flexible hose combined with the ABS speed sensor wire harness clamp from the shock absorber bracket. You must separate the front shock absorber containing the coil spring by removing the two connecting shock absorber-to-bolt-steering knuckle hardware then take out the shock absorber-with-coil-spring using three nuts while removing suspension support No.2. Mount the front shock absorber with coil spring into a vise while inserting the two nuts and bolt into the bracket before compressing the spring with tool number 09727-30021 (09727-00010, 09727-00021, 09727-00031) without using an impact wrench to protect the tool. Use a screwdriver to loosen up the front shock absorber left-hand nut and remove the two nuts from the front support area. After that, pull out the front suspension support sub-assembly together with the dust seal. The technician must examine the shock absorber assembly to check for unusual resistance or sounds after eliminating these suspension components: front coil spring seat upper, front coil spring insulator upper, front coil spring and front spring bumper. Replacement may be required for the shock absorber assembly. Use the identical special service tool to compress the assembly again for installing the front spring bumper and shock absorber assembly front LH and front coil spring while ensuring proper seating of the lower end in the spring lower seat gap. First, install the front coil spring insulator upper with "a" marker facing external direction while placing the front coil spring seat upper with "OUT" marker visible from the outside before installing the front suspension support dust seal and sub-assembly. Secure the front support to front shock absorber left-hand nut using a new center nut and a torque of 33 Nm (340 kgf-cm, 25 ft. lbs.) before removing the special service tool to apply MP grease on the suspension support. Secure the front support to front shock absorber left-hand nut with a new center nut then torque it to 33 Nm (340 kgf-cm, 25 ft. lbs.) during removal of the special service tool. You can then grease the suspension support for installation of the front suspension support dust cover and front shock absorber with coil spring by using suspension support No.2 with three nuts torqued to 39 Nm (400 kgf-cm, 29 ft. lbs.). Afterward, connect the assembly to the steering knuckle and fasten it with two bolts and nut by ensuring the bolt stability before tor Use 29 Nm torque when reinstalling the flexible hose while torquing the front wheel to 103 Nm and cowl top panel outer to 5.0 Nm which enables hose and wire harness reconnection. The service requires reinstalling the windshield wiper link assembly and its components with both cowl top ventilator louvers while also installing the hood to cowl top seal and both front wiper arms. Front wheel alignment should be inspected before adjusting the alignment. Disposing of the shock absorber requires that the rod extends fully before drilling a hole into the cylinder while wearing proper safety equipment because molten metal fragments may be present. The gas is colorless and odorless with no poisonous properties.
