Pontiac 17983984 Engine Mount

To check the transaxle mounts, raise the vehicle and secure it on jackstands, then observe the mount while an assistant manipulates the transaxle or use a pry bar to test for movement; if the rubber separates from the metal plate or if the case only moves up, replacement is necessary. Begin the replacement by disconnecting the negative battery cable and supporting the transaxle with a jack. For the forward transaxle mount, remove the bolts connecting the forward support bracket to the transaxle, then take off the mount-to-support bracket nut and the mount-to-cradle nuts, followed by the removal of the forward support bracket and the mount itself. Position the new mount and install the mount-to-cradle nuts loosely, then place the transaxle support bracket and install the mount-to-support bracket nut and the bracket-to-transaxle bolts loosely. Ensure all mounting hardware is loose, lower the jack until the transaxle centers the mount, and then tighten the hardware to the specified torque before reconnecting the negative battery cable. For the rear transaxle mount, repeat the process of disconnecting the negative battery cable and supporting the transaxle, then remove the rear support bracket-to-transaxle bolts, the mount-to-support bracket nut, and the mount-to-cradle bolt nuts, followed by the support bracket and the mount. Install the new mount and secure the mount-to-cradle bolt nuts loosely, then position the rear support bracket and install the mount-to-support bracket nut and bracket-to-transaxle bolts loosely. Again, ensure all mounting hardware is loose, lower the jack until the transaxle centers the mount, tighten the rear mounting hardware to the specified torque, and reconnect the negative battery cable.
