How to Service and Repair a Tail Pipe and Muffler with a Fire Suppression System on Mercury Grand Marquis?

The first step for muffler and tailpipe service requires depowering the fire suppression system for safety reasons. Park the vehicle at neutral gear position on the hoist platform. Start by taking off the lateral rear suspension arms and rear coil springs followed by rear suspension lateral nuts and clamp retention. You should then detach the two nuts and clamp and tighten them to 45 Nm (33 ft. lbs.) when reinstalling them. Go through the isolator to check for damage and deterioration while conducting an immediate replacement if necessary. Separate the isolator. A precise turning motion of the muffler and tailpipe assembly counterclockwise against the rear axle will let you remove it with its attached isolator. New exhaust fasteners should be employed for installation but the tightening will occur after all components are positioned. The fasteners should be alternately tightened following specifications to achieve uniform drawing power on the flange connections. The vehicle owner needs to perform a repower operation on the fire suppression system after finishing installation work.
