Coil Spring, Rear

All-wheel drive vehicle rear suspension coil spring replacement requires first measuring the hub center-to-fender lip distance when the vehicle rests on flat ground. Sedans need their luggage compartment rear trim panel together with the correct side trim panels removed but wagon owners must remove the third row safety belt anchor-to-floor bolt trim cover. To proceed with the task remove first the shock absorber-to-upper mount nut followed by taking off the wheel together with the tire. To prevent brake hose damage the brake caliper and anchor plate assembly should not be supported through the brake hose. Instead, remove the brake caliper anchor plate bolts and secure the assembly with mechanic's wire. Index-mark the coil spring position on the shock absorber and upper spring isolator for reference during installation. Use jackstands to lower the vehicle after placing a suitable floor jack at the shock absorber mount on the lower arm to raise it while compressing the spring. Start by removing the trailing arm-to-wheel knuckle bolt which becomes waste material before you can loosen the trailing arm-to-subframe bolt and remove the bottom arm-to-wheel knuckle bolt as discarding waste material completes the procedure. Take the shock absorber lower bolt outside and discard it through removal of the floor jack. Pull the shock absorber along with its attached spring off the lower arm while being cautious before discarding the components. When installing the upper spring isolator you must place it onto the spring before securing it with duct tape. The coil spring must reach identical alignment by following the index marks from removal and the installation of new shock absorbers should replicate these marks. Fasten a new bolt to the lower arm before positioning the shock absorber and spring assembly while tightening this bolt to 105 Nm (77 lb-ft). Start by placing the floor jack beneath the lower arm near the shock absorber mount and raise the suspension gently until spring top reaches the upper shock absorber mount. Before moving on, receive help to elevate the lower arm portion while guiding the shock absorber combination until the absorber rod becomes centered inside the upper mount bushing. To secure the new upper shock absorber-to-mount nut you must tighten it to 52 Nm (38 lb-ft). The procedure requires raising the floor jack to reach correct curb height whereas you install the new lower arm-to-wheel knuckle bolt loosely before torquing it to 110 Nm (81 lb-ft). Raise the floor jack until the trailing arm/wheel knuckle is properly aligned with the new trailing arm-to-wheel knuckle bolt loosely installed. After the wheel hub reaches the proper curb height on the floor jack the trailing arm-to-wheel knuckle bolt requires 105 Nm (77 lb-ft) tension while concurrently tightening the trailing arm-to-subframe bolt to 110 Nm (81 lb-ft). The removal of the floor jack and jackstands allows for positioning the brake caliper before installing anchor plate bolts with tightening torque set at 110 Nm (81 lb-ft). As the last step install the wheel together with the tire then proceed to install the third row safety belt anchor-to-floor bolt trim cover for wagons and the luggage compartment rear and side trim panels for sedans.
