2006 Cadillac XLR Rear Crossmember Parts Questions & Experts Answers

• Q: How to replace the Rear Crossmember in the rear suspension on 2006 Cadillac XLR?

  A: Begin the rear suspension crossmember replacement by lifting up and supporting the vehicle and removing both tire and wheel assemblies. First disconnect all wheel speed sensors from their harnesses along with coils from park brake cables and remove electrical connectors from esc Shock Absorber harnesses when present. Beginning the process you should remove the rear suspension position sensors and inner tie rod end studs from the Rear Crossmember and lower control arms from the crossmember. Lower control arms, rear suspension knuckles, and tie rods will require support before separating the transverse spring from its position. Install the j 42055 transmission support fixture (J 42055) on a transmission jack then position the fixture securely to support the transmission. Support the crossmember first by disconnecting electric harnesses and brake tubing followed by removing the lower mount nuts. Position a transmission jack underneath to hold the crossmember. Handle all tasks with hand tools only to unscrew the mounting nuts at the Rear Crossmember before extracting the component from the vehicle and discarding the mounting nuts. During installation align the crossmember dowel pins to the frame rails and transaxle mount studs to the crossmember before using new crossmember mounting nuts. Use only hand tools to install and torque new rear suspension crossmember mounting nuts to 110 n.m (81 lb ft). Remove the j 42055 transmission jack from both the transmission and crossmember before connecting all electrical harness retainers and brake pipe retainers to their respective locations on the crossmember. Position the transaxle mount lower nuts before installing the transverse spring and lower control arms and inner tie rod end studs with the rear suspension position sensors. Whenever possible connect electrical connectors to esc Shock Absorber harnesses if present and park brake cables to actuator levers in addition to wheel speed sensor harness connectors. After installation of tires and wheels complete vehicle lowering then perform measurements to adjust rear trim height before conducting a wheel alignment procedure.
