  Q: How to Service and Repair the Rear Crossmember on Lincoln Town Car?

  A:

  The first step for transmission support crossmember repair and service requires placing the vehicle in neutral position while using a hoist system. The service process begins by first removing the connector from each HO2S sensor followed by removal of the catalyst monitor connectors before uninstalling bolts attaching the exhaust flange to the Catalytic Converter. The same process should then be performed on the LH side after disconnecting the LH HO2S sensor connector and the LH catalyst monitor connector then removing both bolts from the LH exhaust flange and the LH catalytic converter. Before working on the transmission you must remove its rear insulator nuts and then use an appropriate transmission jack to secure it. Clear away both bolts from the RH and LH crossmember before extracting the parking brake cable bracket. It is necessary to gently pry the crossmember from its pocket but avoid damaging the structure as you lower both sides to remove it. Install the crossmember by inserting the left-hand side first into its pocket where you should secure the bolts loosely then follow with the right-hand side bolts. Next install the parking brake cable bracket before torquing it to 55 Nm (41 ft. lbs). Place the transmission onto the crossmember then fasten its rear insulator nuts to 30 Nm (22 ft. lbs) torque. First install a new gasket to the RH catalytic converter assembly before placing it in position while loosely installing its bolts. First tighten the RH exhaust flange nuts to 48 Nm before tightening the RH exhaust bolts to 40 Nm. The technician will connect the RH HO2S sensor connector together with the RH catalyst monitor connector. Follow the same gasket installation process for the LH catalytic converter assembly before installing the bolts without torque then securing the LH exhaust flange nuts with 48 Nm (35 ft. lbs) before torquing LH exhaust bolts to 40 Nm (30 ft. lbs). Start by connecting the LH HO2S sensor connector as well as the LH catalyst monitor connector.
