I removed the front flex disk without touching the exhaust or propeller shaft. I couldn't put in the new flex disk so I dropped the exhaust and center bearing. In retrospect, I think I could have put in the new flex disk if I dropped the rear transmission crossmember (4 bolts). Support the transmission on a jack and see if you can move it enough. Don't move it too much since all the hoses are still in place. Also, the fan might hit the radiator.
The exhaust was already off when I did the rear so I don't know if it would have been possible to change the rear with the exhaust in place.
This was all on the SD. The exhaust of the SE is considerably more difficult to remove. That's probably why you ask
