Loosen the rear wheel lug nuts, raise the vehicle, place it securely on jackstands, and remove the wheel. To disconnect the outer end of the upper arm from the knuckle, remove the nut from the balljoint stud at the knuckle, use a two-jaw puller to separate the balljoint stud from the knuckle, and remove the two mounting bolts from the inner end of the arm before removing the upper arm. Inspect the bushing at the inner end of the arm for cracks and check the balljoint at the outer end for excessive freeplay; if either is worn, have a dealer replace it. Installation is the reverse of removal, ensuring all fasteners are tightened to the specified torque values. For the lower arms, remove the through bolt that attaches them to the knuckle, disconnect any brake hoses or cables, and remove the pivot bolts that attach the inner ends to the chassis before removing the lower arms. Inspect the lower arm bushings for cracks and deterioration, and replace any worn components through a dealer. Installation follows the reverse order of removal, with all fasteners tightened to the specified torque values. For the trailing arm, disconnect the brake hose and parking brake cable brackets, remove the stabilizer bar link, and take out the four bolts that attach the trailing arm bracket to the knuckle, followed by the pivot bolt that attaches the forward end to the chassis before removing the trailing arm. Inspect the bushings at both ends of the arm for cracks or deterioration and have them replaced by a dealer if necessary. Installation is the reverse of removal, ensuring all fasteners are tightened to the specified torque.
