• Q: How to replace the Exhaust Muffler with Resonator, Exhaust, and Tail Pipe on a with LZ9 or LGD (3.9L) on 2010 Buick Lucerne?

  A: A successful replacement of an exhaust Muffler with resonator, exhaust, and Tail Pipe requires vehicle elevation combined with proper suspension maintenance. Always support the exhaust system correctly before you remove the Muffler to Catalytic Converter nuts. Start by unbolting the center Exhaust Hanger from the rear suspension support bracket then unfasten the rear Exhaust Hanger bracket to rear compartment rail bolt. Assistance helps you lower the exhaust system then remove it completely while the Catalytic Converter to Muffler gasket needs disposal. Drain the rear Exhaust Hanger to Exhaust Hanger bracket nut and separate the rear Exhaust Hanger bracket from its position on the rear Exhaust Hanger. Fastener caution must be followed when securing the rear Exhaust Hanger bracket to the rear Exhaust Hanger during installation. Fasten the rear Exhaust Hanger's nut to the Exhaust Hanger bracket using torque setting at 30 nm (22 lb ft). Secure a brand new Catalytic Converter to Muffler gasket over the studs then ask for help while raising and installing the exhaust system. Tighten all Catalytic Converter nuts before installing the rear Exhaust Hanger bracket to its bolt in the rear compartment rail. Apply 50 nm (37 lb ft) torque to this fastener. Lift the vehicle while you install the rear suspension support bracket bolts with 30 nm (22 lb ft) torque and then adjust the Muffler to Catalytic Converter nuts to 25 nm (18 lb ft).
