Nissan 55501-ZQ00A Arm Assembly

On Armada models equipped with a rear auto-leveling suspension, turn the ignition key to the OFF position before raising the vehicle. The manufacturer recommends using new locknuts on the control arm pivot bolts and the bat/joint pinch bolt during installation. Loosen the wheel lug nuts, raise the vehicle and support it securely on jackstands placed under the frame rails. Remove the wheel. If you're working on a 4WD model, remove the driveaxle. Detach the stabilizer bar link from the lower control arm. Remove the shock absorber lower mounting bolt. To remove the lower control arm, remove the pinch-bolt securing the lower balljoint, then use a small puller, or equivalent, to push the ballstud out of the control arm. It's also possible to pry the control arm from the steering knuckle to separate them. Mark the positions of the lower control arm pivot fasteners on both sides relative to the frame, then hold the bolts and remove the locknuts and discard them. Carefully inspect the control arm bushings for hardening, excessive wear and cracks. If they appear to be worn or deteriorated, replace the control arm. Installation is the reverse of removal. Use new locknuts for the balljoint pinch-bolt and the control arm pivot bolts. Align the marks made, then tighten all fasteners. Have the front wheel alignment checked and, if necessary, adjusted.
