How to Properly Service and Repair a Muffler and Tail Pipe on 2009 Ford Crown Victoria?

The first step in muffler and tailpipe service is to disable air suspension electrical power to avoid sudden air spring inflation or deflation which might cause vehicle shifts that result in severe personal injury risks. Operation of the air suspension should begin with disabling the air suspension switch. Position the vehicle with the transmission in the NEUTRAL gear on a hoist. Use the provided cut marks on the tailpipe before you detach two nuts and the exhaust damper (if present) and the exhaust inlet pipe-to-muffler clamp which requires you to discard these nuts. Follow the installation procedure by torquing new nuts to a torque value of 48 Nm (35 lb-ft). Separate the muffler and tailpipe from their connections with the exhaust isolators. Measurement of isolator condition should be performed because worn or damaged isolators require replacement. Start by fitting the tailpipe while attaching its isolator and moving to install the muffler followed by its isolator attachment. New exhaust fasteners should be installed first without tightening until the complete assembly is in place and then tightened to specific torque specifications while switching the order of fastener tightening for equal flange alignment which connects the muffler and tailpipe with a final torque of 33 Nm (24 lb-ft). Complete the connection of the exhaust inlet pipe toward the muffler by installing a clamp alongside an exhaust damper if present along with 2 new nuts to achieve a torque value of 48 Nm (35 lb-ft). You must activate the air suspension switch when it is available.
