2005 Chevrolet Corvette Rear Crossmember Parts and Q&A

• Q: How to replace the Rear Crossmember in the rear suspension on 2005 Chevrolet Corvette?

  A: First lift your vehicle then support it and disconnect all tire and wheel parts. Disengage wheel speed sensor harness connectors when disconnecting park brake cables from actuator levers and electronic suspension control (ESC) shock absorbers harnesses when equipped. Follow this sequence to replace the crossmember: disconnect first the rear suspension position sensors, the inner tie rod end studs and lower control arms from their crossmember attachment. Begin by supporting the lower control arms and tie rods and rear suspension knuckles before breaking free the transverse spring. Position the transmission support fixture (J 42055) onto a transmission jack before placing and securely fastening it to the transmission for support. Disassemble all electrical harness retainers and brake pipe retainers from the crossmember before using a transmission jack to position it underneath the Rear Crossmember. Secure the transmission jack in place. Use only hand tools to remove the Rear Crossmember mounting nuts then discard them. Installation requires the correct alignment of crossmember dowel pins to frame rails plus transaxle mount studs to the crossmember using new crossmember mounting nuts. Through manual operation only install the new rear suspension crossmember mounting nuts before tightening them to 110 n.m (81 lb ft). Remove the transmission support fixture (J 42055) from the transmission followed by removing the jack from the crossmember. Reinstall all electrical harness retainers and brake pipe retainers onto the crossmember before installing the transaxle mount lower nuts and transverse spring and lower control arms and inner tie rod end studs. If your vehicle includes esc Shock Absorber harnesses, install rear suspension position sensors before connecting electrical connectors to the esc Shock Absorber harnesses and attaching park brake cables to actuator levers followed by reconnecting the wheel speed sensor harness connector. After installation of tires and wheels you should lower the vehicle to perform measurements for rear trim height adjustment and complete rear wheel alignment procedures.
