REMOVAL & INSTALLATION
The following applies to exhaust systems using clamped joints. Some models, use welded joints at the muffler. These joints will, of course, have to be cut.1968-79 Models
- Raise and safely support the rear end on jackstands placed under the frame. Allow the rear axle to lower to the full length of its travel.
- Remove the U-bolt clamping the inlet pipe to the muffler. These may have to be cut if they excessively rusted.
- Unbolt the rear support bracket from the muffler.
- Unbolt the intermediate support bracket from the muffler.
- Remove the muffler outlet clamp and remove the muffler. If the muffler will not move, try turning the unit from side to side. If it still will not come off, the unit will have to be cut.
- When the muffler is removed, clean the section of exhaust pipe where the section will be joined to it. The cleaner it is, the easier it will be to fit the section.
- Installation is the reverse of removal. Always use new clamps. Always install all parts loosely until they are aligned and all clearances are satisfied. Tighten the support bracket bolts to 14 ft. lbs. (19 Nm); the flange nuts to 30 ft. lbs. (41 Nm).
