• Q: How to service and repair the muffler and tailpipe on 2004 Ford Expedition?

  A: Start the repair process of muffler and tailpipe by executing the following steps when the vehicle remains in NEUTRAL position on a hoist. Detach the isolator while loosening a clamp before taking off extension pipes or resonator units should they be installed. The four nuts and two stabilizer bar brackets need to be removed until the bar remains suspended from the links. Use an appropriate jack stand to support the muffler before you detach both isolators from their position. Throw away all existing bolts and flag nuts. When you direct the muffler outlet across the rear axle ensure you avoid touching the axle boots to prevent any harm to them. You should first clean both the inlet pipe and catalytic converter mating surfaces before uninstalling the muffler and tailpipe assembly. New fasteners together with gaskets need to be installed along with examinations for wear or damage of exhaust hanger isolators followed by replacements if required. Re-installation of the exhaust system requires performing the steps in reverse order to installation.
