REMOVAL & INSTALLATION
- Detach both lower shock absorbers from the mounts.
- Block the two front wheels, then raise the vehicle at the frame lift points to allow the axle full downward travel. This will provide the clearance necessary to remove and replace the muffler and pipe. Safely support the rear of the vehicle on jackstands.
- Spray all muffler assembly fasteners with penetrating oil and allow the oil to soak in for 5 to 10 minutes.
- Remove the rear converter-to-muffler pipe flange connection attaching fasteners.
- Remove the attaching fasteners from the rear hanger assembly to the tailpipe support.
- Pull the muffler assembly rearward in order to detach it from the catalytic converter.
- Remove the mounting bolts from the intermediate hanger assembly to the muffler support.
Transfer all heat or grass shields to the new exhaust components being installed, if necessary. The muffler heat shield is banded to the muffler body. New clamps must be used for reassembly.
- Position the muffler and tailpipe over the rear axle and loosely attach the intermediate support bracket.
- Position the muffler inlet pipe flange against the converter flange, then install, but do not tighten, the attaching nuts.
- Install the rear muffler support bracket and install the attaching screws loosely.
- Position the exhaust components for proper clearance and fit, then, starting at the muffler inlet pipe connection, tighten all nuts and bolts securely.
- Assemble the lower shock absorber attachments.
- Check the exhaust system for leaks, as follows:
- Start the engine and allow it to idle.
- Have an assistant hold a shop towel against the end of the exhaust tailpipe.
- Without actually touching the exhaust system, run your hand closely along the exhaust system joints to feel for any escaping exhaust gases. If blowing air is felt coming from one of the exhaust system joints the system must be disassembled and reassembled with new gaskets or clamps.
- Lower the vehicle and remove the wheel blocks, if necessary.
