How to service and repair the muffler and tailpipe on Mercury Grand Marquis?

Before repairing or servicing the muffler and tailpipe operators need to disable air suspension electrical power because unexpected air spring movement could shift the vehicle. You must switch off the air suspension and move the vehicle to NEUTRAL mode on a hoist. Use a suitable exhaust cutter to perform the separation between the muffler and tailpipe after removing the clamp. Flexible elements are evaluated for damage or wear so that the process calls for a new insulator replacement before detaching the insulator to remove the tailpipe. Complete another inspection round on the muffler before installing fresh exhaust fasteners by restraining them until the component assembly phase. The installation ends with a reverse order of removal beginning with the fasteners that are first tightened to spec without excessive force then alternately tightened to achieve uniform flange fitting. The application of oil or grease-based lubricants on insulators should be avoided since this deterioration process can result in exhaust hanger insulator separation from the bracket when the vehicle operates.
