Chevrolet 22816872 Rear Coil Spring

If the struts or coil springs show signs of wear such as leaking fluid, loss of damping capability, chipped, sagging, or cracked coil springs, it is important to explore all options before starting any work. To disassemble, the strut and spring assembly should be removed and the strut clevis bracket portion should be mounted in a vise. The damper shaft nut should be unscrewed while holding the shaft with an appropriate tool. The bearing in the spring seat should also be checked for smooth operation. The dust boot and rubber bump stop should be slid off the damper shaft and inspected for deterioration. The compressed spring should be carefully lifted and set aside. To reassemble, the damper rod should be extended and the rubber bump stop and dust boot should be installed. The compressed coil spring should be placed onto the lower seat of the damper, with the end of the spring resting against the raised stop. The upper insulator and spring seat should be installed, followed by the upper mount and mounting nut, which should be tightened to the proper torque specifications.

To remove the coil spring and jounce bumper, start by loosening the wheel lug nuts and raising the vehicle on jackstands. Support the lower control arm with a floor jack and disconnect the stabilizer bar link on 2016 and later models. Remove the shock absorber lower mounting nut and bolt, as well as the lower control arm-to-knuckle nut and bolt and the upper control arm-to-lower control arm link bolt. Lower the floor jack slowly to fully extend the coil spring and remove it along with the jounce bumper from the suspension arms. Inspect the spring seats and jounce bumper for wear and damage, replacing them if necessary. Check the coil spring for any nicks or cracks. To install, reverse the removal steps and replace all fasteners with new ones. Use the floor jack to raise the lower control arm to simulate normal ride height and tighten all fasteners to the proper torque specifications. Finally, install the wheel and lug nuts and lower the vehicle, tightening the lug nuts to the proper torque.
