Shock Absorber

Services and repairs of shock absorber and spring assemblies need a starting point which requires measuring the hub center to fender lip distance from a level parked vehicle. The interior trim requires removal to reach the upper shock absorber nut before discarding the upper shock absorber-to-mount nut. Start by taking out the wheel assembly followed by front suspension support using an appropriate jackstand. You should provide appropriate support to the rear brake caliper since it needs to remain stationary during the removal of anchor plate bolts and while placing the caliper to the side. First position a jackstand underneath the wheel knuckle at its attachment point with the trailing arm yet raise the knuckle so the toe-link becomes parallel to the ground. To proceed with the removal begin by removing the trailing arm-to-knuckle bolt before manually lowering the jackstand then disposing of the trailing arm-to-subframe bolt. Position a jackstand under the lower shock absorber mount to raise it while compressing the shock absorber and spring after which you should remove the lower arm-to-knuckle bolt and loosen the shock absorber and spring assembly lower bolt before lowering the jackstand. Remove the shock absorber lower bolt then drop the lower arm while gripping the spring assembly to take away the assembly. Place the spring onto the upper rubber spring seat and position them both on the shock absorber before fitting the assembly correctly against the upper mount. Position the lower arm underneath the assembly then secure a new shock absorber lower nut and bolt but do not tight them at this time. Start by lowering the vehicle partially before placing a floor jack under the lower arm and raising it so the shock absorber top reaches the upper mount. Proceed to raise the vehicle together with help until the shock absorber properly seats in place, then install a new shock absorber-to-mount nut and torque it to 83 Nm (61 ft. lbs.). After vehicle elevation install the interior trim before removing the floor jack then elevate the vehicle once more. Clench a jackstand to the wheel knuckle then elevate the wheel hub to reach proper curb height. After tightening the lower arm-to-subframe bolt to 125 Nm (92 ft. lbs.), install the lower arm-to-knuckle bolt while torquing it to 160 Nm (118 ft. lbs.). Loosely attach the bolt between trailing arm and wheel knuckle then raise the jackstand until the trailing arm meets the subframe bushing. Place a new trailing arm-to-subframe bolt first then tighten it to 110 Nm (81 ft. lbs.) while the trailing arm-to-knuckle bolt and shock absorber lower bolt require tightening to 110 Nm (81 ft. lbs.). Lower the wheel and connect the brake caliper anchor plate bolts while torquing them to 100 Nm (74 ft. lbs.).
