Coil Spring, Rear

The beginning of racking the rear shock absorber and spring assembly for a 2WD vehicle demands initial measurement of the center-hub to fender lip distance with the vehicle resting at level ground. First remove the interior trim to expose the upper shock absorber nut and keep this nut for disposal. Lift the vehicle with a suitable jack stand positioned at the front section and take out the wheel along with tire assembly from beneath. Support the rear brake caliper when you take it out from its flexible hose before detaching guide-pin bolts. After installing the brake caliper just tighten it to 31 Nm (23 ft. lbs.). Lift the vehicle to a hoist position then place a transmission jack V-topped underneath the knuckle at its trailing arm attachment point until the toe-link becomes parallel with the ground. First remove the bolt connecting the trailing arm to knuckle followed by lowering transmission jack access to remove the trailing arm-to-subframe bolt. Put the jack under the lower shock absorber mount before you elevate it to compress the shock absorber alongside the spring then remove the lower arm-to-knuckle bolt before you loosen the shock absorber and spring assembly bolt and nut. You should lower and remove the transmission jack following lower nut and bolt discarding then use the jack to swing down the lower arm to reach and remove the shock absorber and spring. Starting the assembly process requires the spring to be taped onto the upper rubber spring seat before the correct placement on the shock absorber followed by a final step of installing the components into position with the upper mount. Position the lower arm while maintaining the proper angle and put in place a new lower bolt while leaving it untightened. After partially lowering the vehicle employ a floor jack to slowly elevate the lower arm so the shock absorber top touches the upper mount. Assistance allows you to keep raising the vehicle until the shock absorber properly seats in place before you install and tighten its new nut to 83 Nm (61 ft.lbs). Move back the interior parts while taking out the floor jack followed by vehicle elevation. After setting the transmission jack under the wheel knuckle position raise it until the wheel hub reaches the proper vehicle height on the curb. Follow up by installing the lower arm-to-knuckle bolt and torque it to 110 Nm (81 ft. lbs.). Transfer the trailing arm to the wheel knuckle position then put in the bolt in a loose state before raising the transmission jack until the arm meets up with the bushing of the subframe. Use a new trailing arm-to-subframe bolt and apply torque to 110 Nm (81 ft. lbs.) before fixing the trailing arm-to-knuckle bolt to 105 Nm (77 ft. lbs.). Partially lower the vehicle while you put in the brake caliper before guiding the guide pin bolts to a torque of 31 Nm (23 ft. lbs.).

Service of the rear shock absorber and spring assembly in AWD vehicles starts with measuring hub center to fender lip distance at vehicle ground level. The interior trim needs removing for access to the upper shock absorber nut before discarding it to take off the wheel and tire assembly. When you handle the rear brake caliper maintain support under it to avoid hanging it from the flexible hose; then unscrew the guide-pin bolts before setting the caliper to the side while tightening it to 31 Nm (23 ft. lbs.) when reinstalling. Install a V-topped transmission jack underneath the wheel knuckle to its trailing arm attachment point and rise the jack until it compresses the shock absorber and spring. Before using the transmission jack, you should remove first the trailing arm-to-knuckle bolt then loosen trailing arm-to-subframe bolt before removing the lower arm-to-knuckle bolt. Discard the lower shock absorber and spring assembly-to-knuckle bolt by first pushing the assembly off the lower arm before removing it. You should start by taping the spring to the upper rubber spring seat before inserting a 76 mm (3 inch) rubber hose piece on the upper shock absorber stud and finally installing the spring and upper rubber seat combination on the shock absorber. Fasten the shock absorber combined with springs to the lower arm by using a new bolt and set torque to 142 Nm (105 ft. lbs.). Make use of the transmission jack to elevate the lower arm as an assistant guides the upper shock absorber stud into the bushing so you can install a new lower arm-to-knuckle bolt loosely. Commercial Automotive Tricks 2020 suggests to raise the jack until the wheel hub matches correct curb height before tightening both lower arm-to-knuckle bolts to 90 Nm (66 ft. lbs.). Begin by placing the jack under the trailing arm connection point then raise it to install a new trail arm-to-knuckle bolt, follow that by tightening it to 105 Nm (77 ft. lbs.) then move to tighten the trailing arm-to-subframe bolt to 110 Nm (81 ft. lbs.). Reinstall the brake caliper along with guide pin bolts at 31 Nm (23 ft. lbs.) before taking out the rubber hose to install a new shock absorber nut tightened to 83 Nm (61 ft. lbs.). The last step involves running the transmission jack off the vehicle completely before adding the wheel and tire assembly. When the vehicle is at floor level, install the shock absorber nut that should be tightened to 83 Nm (61 ft. lbs.) before reinstallation of interior trim components.
