One should begin Muffler (2500) replacement by properly raising and supporting the vehicle. Start by removing the exhaust Muffler right
Catalytic Converter nuts before loosening the exhaust pipe clamp near the left Catalytic Converter. Apply lubrication to insulators at the spots where the Muffler assembly hangers fit in order to simplify removal. You will need help to take out the exhaust system hanger insulators numbered 4 through 6. Pull the Muffler assembly rearward to detach it from the catalytic converters before rotating the Muffler towards the vehicle's front to extract it. The installation process will benefit from additional lubrication of the insulators. You need help moving the Muffler assembly into position for installation over the rear axle. The system should travel backwards to reach the catalytic converters before sliding forward to connect. The insulators required installation onto exhaust system hangers numbered 4, 5, and 6. After installation of the exhaust pipe clamp which secures the left Catalytic Converter use 44 n.m (32 lb ft) torque then install Muffler nuts to the right Catalytic Converter while applying 45 n.m (33 lb ft) torque. Finally, lower the vehicle.
