2006 Toyota Prius Parts Questions & Experts Answers

• Q: How to service and repair the rear shock absorber with coil spring on 2006 Toyota Prius?

  A: You need to begin servicing and repairing the rear shock absorber with coil spring by taking out the rear No. 2 floor board and several other components which include the rear deck floor box, rear deck trim cover, tonneau cover assembly, rear seatback assembly LH, rear No. 1 floor board, rear side seatback frame LH, rear No. 4 floor board, deck floor box LH, deck trim side panel assembly LH and battery carrier bracket and rear wheel. Begin service and repair of the rear shock absorber with coil spring by securing the rear axle beam to a jack platform while protecting it with wood to prevent damage before removing upper bolts as well as lower nut and spacer. Then safely lower the jack to extract the shock absorber. To separate the components secure the piston rod with a 6 mm socket hexagon wrench before loosening the nut but not removing it. Special Service Tool 09727-30021 (09727-00010, 09727-00021, 09727-00031) reaches the coil spring and enables spring compression until it becomes mobile before the removal of the nut along with the No. 1 cushion washer, No. 1 cushion, rear spring front bracket, rear suspension support, rear coil spring insulator upper, and rear No. 1 spring bumper. Check the LH rear shock absorber assembly for abnormal resistance and sound when the rod is compressed and extended using an inspection process while performing a replacement when needed. Reassembly starts by using Special Service Tool: 09727-30021 to compress the coil spring before fitting its end into the shock absorber lower seat followed by installation of rear coil spring insulator upper, rear No. 1 spring bumper, rear suspension support, rear spring front bracket, and No. 1 cushion and its washer with precise alignment. Complete the tightening procedure of the shock absorber piston rod nut until reaching 56 Nm (571 kgf-cm, 41 ft. lbs.) specifications before releasing the Special Service Tool. First attach the rear shock absorber with coil spring to the rear axle beam while tightening the nut just enough before lifting the beam to position the rear spring front bracket stud bolt within the vehicle. Then apply a torque of 80 Nm (816 kgf-cm, 59 ft. lbs.) when securing the two upper side nuts and bolt to the bracket. Reinstall the rear wheel under 103 Nm (1,050 kgf-cm, 76 ft. lbs.) torque then stabilize the suspension by bouncing the vehicle while performing a full torque up to 80 Nm (816 kgf-cm, 59 ft. lbs.) of the rear shock absorber lower side installation nut after lowering the vehicle. After reattaching the negative (-) battery terminal you must implement initialization since some systems need it and check the rear wheel alignment before reinstalling the battery carrier bracket and deck trim side panel assembly LH together with deck floor box LH, rear No. 4 floor board, rear side seatback frame LH, rear No. 1 floor board, rear seatback assembly LH, tonneau cover assembly, rear deck trim cover, rear deck floor box, and rear No. 2 floor board. Completely extend the shock absorber rod prior to drilling a hole in the cylinder to release gas which requires proper safety equipment because of the present metal shards. When unobserved the gas exists as colorless and odorless and shows no harmful effects.
