2007 Toyota Prius Parts Questions & Experts Answers

• Q: How to service and repair the rear shock absorber with coil spring on 2007 Toyota Prius?

  A: All service and repairs on the rear shock absorber with coil spring must start by taking out the rear No. 2 floor board and following it up with the removal of the rear deck floor box and rear deck trim cover and tonneau cover assembly and rear seatback assembly LH and rear No. 1 floor board and rear side seatback frame LH and rear No. 4 floor board and deck floor box LH and deck trim side panel assembly LH and battery carrier bracket and rear wheel. Start by elevating the rear axle beam through a jack system which rests upon a wooden support to protect from damage. Then turn off the two upper shock absorber bolts together with its coil spring and subsequent removal of the lower side nut and spacer. Lower the jack unit for shock absorber removal. To disassemble the piston rod requires usage of a 6 mm socket hexagon wrench that loosens the nut while keeping it in place. The Special Service Tool: 09727-30021 (04727-00021, 04727-00031, 04727-00031) should be used to compress the coil spring after installation. After achieving free movement, remove 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 components. Check the rear shock absorber assembly LH rod for normal resistance and sound during compression and extension by exercising caution to replace if it does not work properly. Install the rear coil spring insulator upper and rear No. 1 spring bumper along with the rear suspension support and rear spring front bracket and No. 1 cushion and No. 1 cushion washer after placing the coil spring end into the shock absorber assembly lower seat with the help of Special Service Tool: 09727-30021 while ensuring all components stay properly aligned. Tighten the shock absorber piston rod nut to 56 Nm (571 kgf-cm, 41 ft. lbs.) using Special Service Tool: 09727-30021 then remove the tool. Secure the rear shock absorber with coil spring to the rear axle beam but first start the nut loosely. After that lift the rear axle beam to install its upper section while securing all fasteners to 80 Nm (816 kgf-cm, 59 ft. lbs.). First reinstall the rear wheel with a torque reach of 103 Nm (1,050 kgf-cm, 76 ft. lbs.) before conducting vehicle suspension bouncing for stabilization and performing final tightness control of the lower side installation nut to 80 Nm (816 kgf-cm, 59 ft. lbs.) when the vehicle is in its lowered position. The task includes reinstalling the battery carrier bracket, deck trim side panel assembly LH, 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, and rear deck floor box before checking the rear wheel alignment and performing system initializations that need battery negative (-) terminal reconnection. The disposal process requires extending the shock absorber rod before drilling a hole into the cylinder while using proper safety equipment due to the non-poisonous colorless and odorless gas.
