To remove the rear sway bar kit on 2009 and earlier models, loosen the rear wheel lug nuts, remove the rear wheels, and detach the sway bar links from the bar. Remove the sway bar bushing bracket fasteners and pull the brackets off the bar. To install, lubricate the bushings and tighten the sway bar link and bracket fasteners to the proper torque. Install the wheels, lower the vehicle, and tighten the 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 bushings, replacing suspension fasteners, and tightening them to the specified torque. Finally, tighten the wheel lug nuts to the torque specifications.

To take down the sway bar kit, first slacken the back wheel lug bolts and obstruct the front wheels to stop the vehicle from moving. After that, lift up the rear end of the car and sustain it firmly on jack stands before removing its back wheels. Then separate rear section of exhaust pipe and parking brake cables from trailing arms. Remove coil springs without unjoining brake calipers from brake hoses. Indicate location of subframe onto chassis and hold subframe with two jacks beneath it. Get rid of all subframe mounting bolts and lower it a little so as to easily reach sway bar kit bracket bolts. Unfasten sway bar links from bar and remove sway bar kit checking if there are any signs of trouble with sway bar bushings. Damaged ones need replacement in case they are damaged by sway bar bushings. Sway bar kit installation requires lubricating them with vegetable oil, replacing all suspension fasteners with new ones, tightening them according to torque specifications properly then finally secure proper torque specifications for brake fasteners and wheel lug nuts.

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.

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.
