Mopar 5105892AD Rear Coil Spring

Loosen the rear wheel lug nuts and raise the vehicle on jackstands. Remove the rear wheels. Remove the rear shock absorber/coil spring assembly. If servicing both shocks, mark the parts right and left. Compress the coil spring with a spring compressor, following the tool manufacturer's instructions. Compress the spring until tension is removed from the upper bracket. Hold the damper shaft with a wrench and remove the damper shaft nut. While keeping the spring compressed, remove the shock through the bottom of the spring and inspect all parts for damage. Replace any damaged parts. Install the parts on the new shock in the following order: lower spring isolator, spring, upper spring isolator, dust shield, jounce bumper, washer, bushing, sleeve, upper mounting bracket, bushing, washer, nut. Ensure the upper mount is oriented correctly. Install the washer and damper shaft nut, tightening to the specified torque. Slowly release tension from the spring by backing off the spring compressor. Ensure the spring has settled in the locator holes and the brackets/mounts are not twisted or off-center. Install the shock absorber/coil spring assembly.

A spring compressor is necessary for this procedure and can be rented from auto parts stores or equipment rental yards. Before starting any work, explore all options if the struts or coil springs show signs of wear. If a problem develops with the strut body, it must be replaced. However, complete strut assemblies may be available on an exchange basis. Check the cost and availability of parts before disassembling the vehicle. To begin the disassembly process, remove the strut and spring assembly. Mount the strut clevis bracket portion in a vise and mark the components for reassembly. Install the spring compressor on the spring and compress it to relieve pressure from the upper mount. Loosen the shaft nut while holding the damper shaft from turning. Remove the nut and upper mount, inspecting the pivot bearing and upper spring seat for damage. Lift the compressed spring from the assembly and remove the dust boot from the damper shaft. Slide the rubber bumper off the damper shaft and check the lower spring isolator for damage. To reassemble, extend the damper rod and install the rubber bumper and dust boot. Carefully place the coil spring onto the damper, aligning it with reference marks. Install the upper spring isolator and seat, followed by the upper mount. Tighten the nut on the damper shaft. Loosen the coil spring compressor and remove it once the top coil is properly seated. Finally, install the strut/spring assembly.
