GM 10391592 Rear Spring Assembly (Rh Proc)

To remove the coil spring and jounce bumper, start by loosening the wheel lug nuts and raising the vehicle with jackstands. Support the lower control arm with a floor jack and detach the stabilizer bar link if necessary. Remove the lower control arm-to-knuckle nut and bolt, as well as the upper control arm-to-lower control arm link bolt. Slowly lower the floor jack to fully extend the coil spring, then remove it along with the jounce bumper from the suspension arms. Inspect the spring seat, jounce bumper, and coil spring for wear and damage, replacing any necessary parts. To install, reverse the removal steps and use new fasteners. Raise the lower control arm with the floor jack to simulate normal ride height, then tighten all fasteners to the specified torque. Finally, install the wheel and lug nuts, lower the vehicle, and tighten the lug nuts to the specified torque.

Before working on worn struts or coil springs, consider replacement options. Check part availability and cost before disassembling the vehicle. To disassemble, remove and mount the assembly in a vise. Use a spring compressor to relieve pressure and unscrew the damper shaft nut. Check rubber parts for wear and replace them if needed. Carefully set aside the compressed spring. To reassemble, extend the damper rod and install the rubber bump stop and dust boot, then place the compressed coil spring onto the lower seat of the damper. Install the upper insulator, spring seat, and upper mount, tightening to the specified torque. Remove the spring compressor tool and install the assembly.

If the struts or coil springs show signs of wear, they must be replaced as they can't be serviced. Before starting, check the cost and availability of parts. To disassemble, remove the strut and spring assembly and mount the strut clevis bracket in a vise. Use a spring compressor to relieve pressure from the upper spring seat. Unscrew the damper shaft nut, remove the nut and upper mount, and check the rubber portion for cracking. Remove the upper spring seat from the damper shaft and inspect the rubber portion and bearing. Check the dust boot and rubber bump stop for cracking and replace if needed. Remove the compressed spring. To reassemble, extend the damper rod and install the rubber bump stop and dust boot. Place the compressed coil spring onto the lower seat of the damper, install the upper insulator and spring seat, followed by the upper mount and mounting nut. Tighten to the proper torque specifications, remove the spring compressor tool, and install the strut spring assembly.

Before disassembling the vehicle, it is recommended to check the cost and availability of parts.
