Start the exhaust Muffler replacement on 4.3l/4.8l/5.3l/6.0l engines by using the frame to lift and lower the rear axle. When a vehicle features three-way Catalytic Converter piping remove the retaining nuts from the Muffler flange. It is essential to remove the left Catalytic Converter from its Muffler flange position by first loosening its clamp and then unthreading the securing nuts. You will have to uninstall the Muffler assembly hanger pins from exhaust hanger insulators because this task usually requires help from two people to manage the heavy exhaust system weight. Raise the Muffler assembly above the rear axle before moving it forward towards the front of the vehicle. The Muffler assembly must be installed by lifting it from the front across the rear axle using two people for assistance if necessary. Screw in the Muffler assembly hanger pins onto the exhaust hanger insulators. The process includes adding a new gasket and installing the retaining nuts to the front of the Muffler while tightening them to 48 nm (35 lb ft). Dual Catalytic Converter pipes require installation of the right converter into the Muffler assembly followed by a 40 lb ft clamp force on the clamp nut. Fit a new gasket and tighten the nuts which connect the left Catalytic Converter to the Muffler while maintaining precise exhaust alignment. Tighten the right Catalytic Converter clamp to 54 nm (40 lb ft) and the Catalytic Converter to Muffler flange nuts to 48 nm (35 lb ft) when the vehicle is lowered.
