To remove the rear sway bar kit on 2009 and earlier models, start by loosening the rear wheel lug nuts and raising the vehicle on jackstands. Remove the rear wheels and detach the sway bar kit links from the bar. Remove the sway bar kit bushing bracket fasteners and pull the brackets off the bar. Inspect the sway bar bushings for any signs of damage and replace them if necessary. To install, lubricate the sway bar bushings with vegetable oil and tighten the link and bracket fasteners to the specified torque. Install the wheels, lower the vehicle, and tighten the lug nuts to the torque specifications. For 2010 and later models with RPO GNC rear suspension, the removal process is slightly different. Loosen the wheel lug nuts, raise the vehicle, and support it on jackstands. Remove the rear section of the exhaust system, parking brake cables, coil springs, and brake caliper. Detach the sway bar kit links and remove the shock absorber lower bolts. Mark the position of the subframe, support it with a floor jack, and remove the subframe mounting bolts. Lower the subframe to access the sway bar kit bracket bolts and remove them. Remove the sway bar kit and inspect the sway bar bushings for damage. The installation process involves lubricating the sway bar bushings, replacing all suspension fasteners, and tightening them to the specified torque. Finally, tighten the brake fasteners and wheel lug nuts to the torque specifications. For models with RPO GNE rear suspension, the removal process is similar to the GNC models. Remove the sway bar kit links, bracket bolts, and the sway bar kit. Inspect the sway bar bushings and replace them if necessary. The installation process involves lubricating the sway bar bushings, replacing suspension fasteners, and tightening them to the specified torque. Finally, tighten the wheel lug nuts to the torque specifications.

During installation, the stabilizer bar and bushings are installed, lubricated with vegetable oil, and positioned with the slit in each bushing facing toward the rear of the vehicle.

To remove the sway bar kit, start by loosening the rear wheel lug nuts and blocking the front wheels to prevent the vehicle from rolling. Then, raise the rear of the vehicle and support it securely on jackstands before removing the rear wheels. Next, remove the rear section of the exhaust system and the parking brake cables from the trailing arms. Remove the coil springs and the brake calipers without disconnecting the brake hoses. Mark the position of the subframe to the chassis and support the subframe with two floor jacks. Remove the subframe mounting bolts and lower the subframe slightly to access the sway bar kit bracket bolts. Detach the sway bar links from the bar and remove the sway bar kit, inspecting the sway bar bushings for any signs of damage. If the sway bar bushings are damaged, they should be replaced. To install the sway bar kit, lubricate the sway bar bushings with vegetable oil and replace all suspension fasteners with new ones, tightening them to the proper torque specifications. Finally, tighten the brake fasteners and the wheel lug nuts to the correct torque specifications.

To replace the sway bar link, start by loosening the front wheel lug nuts and raising the front of the vehicle. Support it securely on jackstands and remove the front wheels. To detach the sway bar link from the strut or the bar, hold the ball stud with an Allen wrench while turning the wrench to loosen and remove the nut. Installation is the reverse of removal, so tighten the nuts to the proper torque specifications. Finally, install the wheels and lug nuts, then lower the vehicle and tighten the wheel lug nuts to the torque. For the sway bar link and sway bar bushings, once the subframe has been removed or lowered sufficiently, remove the sway bar link bracket bolts and separate the bar from the subframe. Installation is the reverse of the removal procedure, so tighten the sway bar link clamp bolts to the torque.
