Some replacement models may include automatic load levelling shock absorbers for the rear axle which are distinguishable by their gross sizes and through which their removal and installation requires lowering of the rear sub frame of one side at a time thus making the undertaking to be more complex than merely changing of the conventional shock absorbers. SRT models come with a rear shock absorber system with accelerometers, specifically for shock, which enables the ADS to change depending on road conditions and vehicle angle; the servicing of this shock is as usual as the other models except the electric connection of the three-wire. First, there is the procedure of removing the wheel lug nuts, lifting the rear of the affected vehicle and placing jackstands on the frame rails-before removing the wheel. Place a floor jack under the spring, to keep the suspension in position for the removal of the shock absorbers, and unscrew the upper bolts of the shock absorber from the frame using penetrating oil if necessary. Subsequently release the lower shock fasteners of the spring link, in case the nut is ruined, utilizing the penetrating oil. Removal is done in a reverse sequence to installation and a lot of care is taken to lift the spring link to mimic normal ride height before tightening the lower shock mounting bolts. During servicing of load-leveling shock absorbers, no interpolation of the exhaust pipes is required; they should be lowered and supported only. For the left shock, take off the rubber hose between the fuel filler neck and the gas tank , and pull the filler neck to one side and for the right shock, drop the exhaust by taking it off from the hangers. Place the car on safety stands by putting a floor jack beneath the two rear differential mounts then unbolt the upper shock nut while the floor jack is lowering down slowly. Remove the lower shock fasteners being mindful to work on one lower shock at a time to not alter rear wheel alignment. The position of the subframe in relation to the chassis, uncover and take out the screws of the subframe at the working side making sure you lower the differential just enough to uninstall the shock absorber. This is due to the fact that lowering the subframe to much will cause damages to the other parts. Before hoisting up the subframe, make sure that the lower shock fasteners are fixed properly; also confirm that coil spring and insulators are correctly positioned and fix the correct size of the mounting bolts used on subframe. Replace all the components, adjust the spring link up to provide normal ride height, tighten the lower shock, make sure all suspension bolts are tightened, and get the alignment checked and done if need be.
