How to replace the muffler on a 1500 Series with a 6.2L engine on GMC Sierra 3500 Classic?

Replacing the Muffler on a 1500 series vehicle with a 6.2l powertrain requires vehicle elevation and proper support before work can commence. Install adjustable jack stands under the rear axle when you need to remove the spare tire. If your vehicle features an 8.6 or 9.5 inch ring gear you need to eliminate the rear axle vent hose together with its swivel clip attached to the rear brake crossover pipe. The vent hose procedure should be followed by owners using a 10.5 inch ring gear. Following the removal of lower bolts and nuts from the rear Shock Absorber you should lower down the rear axle utilizing adjustable jack stands. Before removing the Muffler assembly hangers place lubrication on their 5 insulators. Using assistance remove the insulators (1-3) which are situated on the front intermediate and rear Muffler assembly hangers after which you should remove the insulator from the tail pipe hanger to free the Muffler assembly. Apply lubrication to the five insulators followed by assistered placement of the Muffler assembly before securing each insulator at its appropriate hanger location. These include the hanger for the tail pipe and for the front, intermediate, and rear Muffler assembly hangers. Screw the Muffler nut onto the Catalytic Converter and torque it to 45 n.m (33 lb ft). Using adjustable jack stands, raise the rear axle to install the rear Shock Absorber lower bolts and nuts while tightening them to 95 n.m (70 lb ft). Installation of rear axle vent hose requires models using a 10.5 inch ring gear to connect the vent hose swivel clip to the rear brake crossover pipe. Repetition of this installation must be done for models which have ring gears measuring 8.6 or 9.5 inches. After completing the process you must uninstall the adjustable jack stands and reinstall the spare tire before dropping the vehicle to its original position.
