How to service the muffler and tailpipe on Ford Expedition?

Begin muffler and tailpipe service by putting the vehicle in NEUTRAL mode while hoisting it. Rubbber degradation will occur when you use oil- or grease-based lubricants on isolators. Service technicians must loose the clamp and separate the isolator from the hanger followed by removal of the extension pipe for Expedition models or the resonator for Navigator models before tightening the clamp to 48 Nm (35 ft. lbs.) forces. You should proceed with removing the 4 nuts and 2 stabilizer bar brackets after which you can let the bar hang from the links and tighten to 55 Nm (41 ft. lbs.) during the repair. Once you separate the isolators from the muffler use new fasteners for installation by tightening them to 48 Nm (35 ft. lbs.). When you direct the muffler outlet over the rear axle avoid touching the axle boots to prevent harm. The muffler and tailpipe assembly should be removed so you can clean the inlet pipes and converters and always use new fasteners during reinstallation. Inspect exhaust hanger isolators for damage symptoms. Replace them when necessary. Reverse the previous uninstalling steps to execute the installation.
