How to service and repair the muffler and tailpipe on Lincoln Navigator?

The procedure to repair a muffler and tailpipe begins with having the vehicle in NEUTRAL position and placed on a hoist. Start by opening the clamp while pulling apart the isolator from its hanger before taking off the extension pipe (Expedition series) or using the resonator (Navigator line up). The bar becomes suspended from the links after the removal of four nuts and two stabilizer bar brackets. Apply a suitable jack stand to support the muffler before removing the isolators from the muffler and unfastening both bolts and flag nuts which then become waste material. Avoid contacting the axle boots as you direct the muffler outlet across the rear axle to protect from damage. Clean the mating surfaces of clockwise and counter-clockwise inlet pipe and catalytic converter before removing the muffler along with tailpipe assembly. New fasteners should be installed while inspecting exhaust hanger isolators for signs of damage or wear because replacement may be needed. The installation ends by following steps in the reverse order of removal.
