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

  A: The front shock absorber coil spring replacement process starts with removing the front wheel followed by front wiper arm head cap and both front wiper arms. Lift the hood before removing both the cowl top seal together with the cowl top ventilator louver from the left hand side. The front stabilizer link assembly LH needs to disconnect while using a jack to support front suspension lower arm No.1 LH and removing the nut. Unplug the speed sensor front LH after removing its bolt and front flexible hose No. 1. Disassemble the front shock absorber with coil spring after loosening the lock nut (keep the nut attached) while also removing lower side 2 nuts and upper side 3 nuts until the speed sensor disconnects completely. Fasten the front shock absorber with coil spring in a vise through the use of a double nutted bolt then connect Special Service Tool: 09727-30021 (09727-00010, 09727-00021, 09727-00031) to the coil spring before compressing it without an impact wrench. Dismantle the shock absorber assembly LH by removing the lock nut and front suspension support sub-assembly LH and its associated dust seal and coil spring seat upper LH then insulator upper LH and coil spring LH and finally front spring bumper LH. Check the shock absorber assembly for abnormal resistance and sound when compressing and extending its rod before replacing if problems are detected. The installation of front shock absorber assembly begins with front coil spring insulator lower LH followed by front spring bumper LH then compression of front coil spring LH using the Special Service Tool. Install the coil spring into the lower seat before placing the upper insulator and coil spring seat together. Attach the dust seal and sub-assembly but tighten only the new lock nut temporarily. Affix the front shock absorber with coil spring by connecting its 2 bolts to the steering knuckle assembly while lifting with a jack before securing with 3 nuts and 2 nuts to the specified torque values. Pressurize the indicated components with MP grease No.2 as you install the front flexible hose No.1 and speed sensor front LH while installing the front stabilizer link assembly LH. Finish the assembly by putting back the front wheel then add the cowl top ventilator louver LH, hood to cowl top seal, both front wiper arms, and the front wiper arm head cap while inspecting and adjusting the front wheel alignment.
