Cadillac 84356289 Link Assembly, Rear Susp Lwr Trailing

Loosen the wheel lug nuts, raise the vehicle, and support it securely on jackstands while blocking the front wheels to prevent rolling, then remove the wheel. Next, remove the brake caliper and caliper mounting bracket, followed by the rear shock absorber, ensuring to support the lower control arm with a floor jack positioned under the spring pocket throughout the procedure. Remove the upper balljoint nut and use a balljoint removal tool to separate the ballstud from the knuckle. Support the rear differential and sub-frame with a floor jack, loosening the subframe bolts enough to access the upper control arm mounting nut bolts; some items may need to be removed to lower the subframe, but complete removal is not necessary. Remove the mounting nut/bolts from the inner end of the upper suspension arm and take the arm out of the vehicle. For installation, reverse the removal steps and tighten the fasteners to the specified torque, raising the lower arm to simulate normal ride height before tightening the inner pivot bolts/nuts. For the lower suspension arm, remove the coil spring, then take out the lower arm inner nut/bolt and remove the arm, with installation being the reverse of removal and fasteners tightened to the specified torque. Support the lower control arm with a floor jack, then remove the trailing arm-to-knuckle nut bolt and the trailing arm-to-subframe nut bolt before removing the arm, with installation being the reverse of removal and fasteners tightened to the specified torque. On 2008 and later models, it may be necessary to support, unbolt, and lower the front of the subframe to access the inner toe-link bolt; remove the inner toe-link nut bolt, then the outer toe-link bolt before removing the link arm, with installation being the reverse of removal and fasteners tightened to the specified torque.
