2005 Toyota Prius Parts Questions & Experts Answers

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

  A: The process to replace the rear shock absorber with coil spring starts with extraction of the rear floor board No.2, deck floor box rear, deck trim cover rear, tonneau cover assembly, rear seat back assembly LH, rear floor board No.1, rear side seat back frame LH, rear floor board No.4, deck floor box LH, deck trim side panel assembly LH, and battery carrier bracket, along with the rear wheel. First support the rear axle beam with a jack and use a wooden block to protect it while you take out the two nuts and bolt from the upper side of the rear shock absorber with coil spring followed by the nut and spacer from the lower side before gently removing both pieces while the jack stays lowered. Attach a 6 mm socket hexagon wrench to the piston rod of the rear shock absorber assembly LH before you relax its mounting nut. The Special Service Tool: 09727-30021 (09727-00010, 09727-00021, 09727-00031) should attach to the coil spring which can then be compressed until it moves freely before removing the nut and components such as cushion washer No.1, cushion No.1, rear spring front bracket, rear suspension support assembly, rear coil spring insulator upper, and rear spring bumper No.1. The inspection of the shock absorber assembly should involve testing rod compression and extension to detect any irregular sounds or resistance which would require replacement. Special Service Tool 09727-30021 must first compress the coil spring for assembly. Then set the coil spring end inside the shock absorber assembly lower seat followed by installation of rear coil spring insulator upper, rear spring bumper No.1, rear suspension support assembly, rear spring front bracket, cushion No.1, and cushion washer No.1 while maintaining correct alignment. Apply a 6 mm socket hexagon wrench to tighten the piston rod nut to 56 Nm (571 kgf-cm, 41 ft-lbs). Once the torque requirement is reached, remove the Special Service Tool. Insert the rear shock absorber assembly with coil spring to the rear axle beam and tighten the nut just enough to allow the installation of the upper side. Raise the axel beam assembly using a jack while ensuring the rear spring front bracket stud passes through the bracket center hole. Install the rear wheel with a 103 Nm (1,050 kgf-cm, 76 ft. lbs.) torque after which the vehicle should be bounced to stabilize the suspension before tightening the lower side nut fully to 80 Nm (816 kgf-cm, 59 ft. lbs.) while the vehicle is lowered. The last step includes checking rear wheel alignment followed by an initialization procedure using the discharge head lamp. When disposing of the rear LH shock absorber assembly users should first extend the rod before drilling a hole between points A and B of the cylinder while employing appropriate safety gear because metal fragments could be present.
