To install the trailing arm, loosen the rear wheel lug nuts, block the front wheels, raise the rear of the vehicle and support it securely on jackstands. Remove the rear wheel, detach the parking brake cable from the trailing arm, remove the nut and pivot bolt that attach the forward end of the trailing arm to the trailing arm bracket, remove the nut and bolt that attach the trailing arm to the rear knuckle, remove the trailing arm, inspect the trailing arm bushings and have them pressed out and new ones pressed in at an automotive machine shop if they're cracked, hardened or otherwise worn. Installation is the reverse of removal, after the bolts and nuts have been installed raise the rear knuckle with a floor jack to simulate normal ride height, then tighten the trailing arm bolts. The manufacturer recommends using new self-locking mounting nuts when installing the trailing arm.
