• Q: How to replace the Rear Crossmember in the rear suspension support on 2008 Chevrolet Corvette?

  A: Before you replace the rear suspension support crossmember, it starts with lifting and supporting the vehicle. Loosen and remove the tire & wheel assemblies, disconnect the wheel speed sensor harness connectors, park brake cables from the actuators levers, and electrical connectors from electronic suspension control (ESC) shock absorbers the harnesses, if applicable. Pull off the rear suspension position sensors, pull off the inner Tie Rod end studs from the Rear Crossmember, and pull off the lower control arms from the crossmember. You can then support the lower control arms, tie rods, the rear suspension knuckles and remove the transverse spring before you proceed. Mount the drivetrain support fixture (J 42055) and place it upon a transmission jack such that it is mounted and secured to the transmission, whilst supporting the transmission. Take off the transaxle mount lower nuts then disconnect all electrical harness retainers and brake pipe retainers from the crossmember after that position transmission jack under the Rear Crossmember and then fasten it. Using only a hand tool, remove nuts holding the Rear Crossmember in place and put cross member out of the vehicle and discard the nuts. For the installation, set the crossmember dowel pins to the frame rails and the transaxle mount studs to the crossmember and only use new cross member mounting nuts that have to be tightened to 110 n.m (81 lb ft). Take the j 42055 transmission jack off the transmission and the crossmember thereafter reel all the electrical harness retainers and brake pipe retainers to the crossmember. Mount the lower nuts of the transaxle mount, the transverse spring, the lower control arms, and inner Tie Rod end studs to the crossmember and then the rear suspension position sensors. Connect electrical connectors to the esc Shock Absorber harnesses, park brakes cables to the actuator levers and the wheel speed sensor harness connector. Lastly, install the tyre and wheel assemblies lowering the vehicle, measure and adjust the rear trim height if necessary and do rear wheel alignment.
