• Q: How to overhaul the rear shock absorber with coil spring on 2004 Toyota Corolla?

  A: The overhaul process of the rear shock absorber with coil spring starts with removing the rear wheel and spare wheel cover assembly then following with the rear floor finish plate and luggage compartment trim cover inner LH. Remove the 2 nuts and bolt and then the nut along with washer and shock absorber as you support the rear axle beam by using jack. When working on the rear LH shock absorber assembly compression of the coil spring requires the use of Special Service Tool: 09727-30021 without using impact wrenches to prevent tool damage. Remove the nut from the piston rod while holding it with a 6 mm hexagon spanner to eliminate the support plate and cushion along with the spring bracket and upper insulator and suspension support and spring bumper and coil spring. The shock absorber inspection requires extension and compression of the rod to detect irregular resistance or strange noises; replace defective units as needed. You must use Special Service Tool: 09727-30021 once again to compress the coil spring before inserting it into the shock absorber while fitting the lower end into the spring lower seat opening. The spring bumper and suspension support and upper insulator should be placed on the spring bracket and then set the spring bracket to its correct position. You should install cushion and support plate followed by briefly tightening a new center nut before using the Special Service Tool: 09727-30021 to check spring bracket direction and finally tightening the new nut with a 6 mm hexagon wrench to 56 Nm torque (571 kgf-cm, 41 ft. lbs.). The procedure requires first installing the rear shock absorber with coil spring and temporarily tightening its nut and washer. Then install the 2 nuts and bolt with a final torque value of 80 Nm (816 kgf-cm, 59 ft. lbs.). Lower the automobile while installing the rear wheel and perform multiple suspension bouncing movements to achieve stability. Andrew should fully tighten the rear shock absorber coil spring's nut to 80 Nm (816 kgf-cm, 59 ft. lbs.) then inspect the rear wheel alignment. The rear LH shock absorber assembly disposal requires shock absorber rod extension followed by drilling a cylinder hole to ventilate the gas reserve inside but safety measures should be taken to prevent chips and recognize gas properties as colorless, odorless, and non-toxic.
