How to replace the muffler on Chevrolet Trailblazer?

The Muffler replacement process starts with frame brace and spare tire followed by removing the rear axle Tie Rod and rear axle brace. The process continues by removing shock absorber lower mounting bolts before setting them aside. Follow this step by removing the right rear coil spring when present. Remove the Muffler to Catalytic Converter nuts from a 4.2l engine. The Muffler to Catalytic Converter nuts require removal according to the engine type if you have a 5.3l or 6.0l vehicle. You need assistance to detach the Muffler's exhaust insulators (1, 3, and 4) from the hangers before you remove the entire Muffler assembly from the vehicle. Position the Muffler assembly back onto the vehicle with help before you reattach exhaust insulators (1, 3, and 4) onto the Muffler hangers. When working with 5.3l or 6.0l engines install the Muffler to Catalytic Converter nuts while torquing them to 45 n.m (33 lb ft). When installing the Catalytic Converter to Muffler nuts on a 4.2l engine maintain a torque setting at 45 n.m (33 lb ft) before continuing. Install the right rear coil spring when present and position the shock absorbers before installing the lower mounting bolts. To complete the installation you must reinstall the rear axle brace together with the rear axle Tie Rod and spare tire before remounting the frame brace.
