  Q: How to replace the Rear Crossmember on Buick Terraza?

  A:

  Begin by raising and supporting your vehicle and proceed by taking off both rear tires and wheels. Install a utility stand behind the rear Differential carrier before removing the mounting bolts between the carrier and the Rear Crossmember. The next step requires removal of the rear suspension knuckle followed by elimination of the wheel speed sensor harness connection to the lower Control Arm and Rear Crossmember. Begin by removing the rivets connecting the park brake cable to the Rear Crossmember before extracting the automatic level control (ALC) height sensor and link from the combination of crossmember bar and lower Control Arm. Then secure the alc wiring harness out of the operating area. A utility jack will support the Rear Crossmember before removing its mounting bolts to lower the crossmember down. You must first remove the rear stabilizer shaft followed by the rear axle upper and lower control arms and Tie Rods from the Rear Crossmember. Start the installation process by putting tie rods onto the crossmember before adding the lower and upper control arms for the rear axle and completing with installation of the rear stabilizer shaft. Use guide pins through rail holes to align the Rear Crossmember before inserting the Rear Crossmember mounting bolts which require 130 n.m (96 lb ft) torque. Mount the alc height sensor to both the crossmember and lower Control Arm followed by the Parking Brake Cable installation to the Rear Crossmember. Reposition the rear suspension knuckle followed by wheel speed sensor harness installation onto the Rear Crossmember and lower Control Arm then reinstall rear tires and wheels on the lowered vehicle. Conduct examination for rear wheel alignment then perform adjustments if needed.
