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

  A: The overhaul process for the front shock absorber with coil spring begins by taking off the front wheel followed by disconnecting the front stabilizer link assembly LH by removing its nut and disconnecting it to the shock absorber assembly front LH. Supporting the ball joint with a hexagon (6 mm) wrench will prevent joint movement. If the front shock absorber requires no disassembly then the lock nut needs not be loosened. To detach the front flexible hose No.1 along with speed sensor front LH wire harness, remove the connecting bolt initially. Afterwards, unfasten the 2 lower side nuts and 3 upper side nuts securing the front shock absorber with coil spring while keeping the remaining bolts in place. Untighten the lower side bolts with caution as the collar will drop if there is a front suspension upper brace center present. The front shock absorber with coil spring must be secured in a vise through clamp placement on the double nutted bolt attached to the absorber bottom bracket. The Front Coil Spring LH needs to be compressed with Special Service Tool: 09727-30021 (09727-00010, 09727-00021) without using an impact wrench to maintain tool integrity before removing the Front Suspension Support Sub-Assembly LH, Front Suspension Support Bearing LH, Front Coil Spring Seat Upper LH, Front Coil Spring Insulator Upper LH, Front Coil Spring LH, Front Spring Bumper LH, and Front Coil Spring Insulator Lower LH from the Shock Absorber Assembly Front LH. The shock absorber assembly undergoes inspection following repeated compression and extension of its rod at least 4 times for detecting abnormal resistance or sounds and requires replacement if any abnormality occurs. For absorber assembly installation first place the front coil spring insulator lower LH onto the shock absorber assembly front LH while attaching the front spring bumper LH to the piston rod before compressing the front coil spring LH by using the same Special Service Tool. Assemble the front coil spring by lowering its end through the gap of front coil spring lower LH followed by front coil spring insulator upper LH then front coil spring seat upper LH which must have its mark facing outward and a new front suspension support bearing LH. The front suspension support sub-assembly LH should be installed with its mark facing outward while a new lock nut receives temporary tightening before the Special Service Tool can be used to release the coil spring. Secure the front shock absorber with coil spring into position first through the upper portion where three nuts must be torqued to 85 Nm (867 kgf-cm, 63 ft. lbs.) before fixing the two bolts and two nuts on the lower section while maintaining bolt rotation limits and torquing them to 210 Nm (2,140 kgf-cm, 155 ft. lbs.). Attach the front flexible hose No.1 and speed sensor front LH using the bolt and torque it to 19 Nm (192 kgf-cm, 14 ft. lbs.). After that, completely tighten the lock nut to 49 Nm (500 kgf-cm, 36 ft. lbs.). The procedure ends with installation of the LH front stabilizer link assembly and its nut torque set to 74 Nm (755 kgf-cm, 55 ft. lbs.). Reinstall the front wheel afterward with torque at 103 Nm (1,050 kgf-cm, 76 ft. lbs.). Complete the task by inspecting and adjusting the front wheel alignment.
