How to Properly Service and Repair a Muffler and Tail Pipe on Mercury Grand Marquis?

Service of the muffler and tailpipe starts when the vehicle sits in neutral position on a hoist. Prior to hoisting or jacking or towing activities the air suspension electrical power needs to be disabled because unexpected air spring movement can shift the vehicle position. First disable the air suspension system through its switch. After the removal of the two nuts and clamp install them at 45 Nm (33 ft. lbs.) tightness. A suitable exhaust cutter tool helps cut the muffler from the tailpipe. Inspect the isolator before changing it if needed then detach the isolator to remove the tailpipe. The muffler replacement procedure should be executed again. The installation of new exhaust fasteners requires waiting until all components are ready before executing any tightness adjustments when possible. The final tightening of fasteners should reach 33 Nm (24 ft. lbs.) after performing even distribution through alternate tensioning per specification. The use of oil-based or grease-based lubricants on the isolators should be avoided since these products will deteriorate the rubber material which could cause it to separate from the exhaust hanger bracket during vehicle operation.
