Just got in from the shop. Just in case anyone else runs into this problem, I removed the 8 bolts that hold the hydro and rear end to the frame and carefully lowered the rear end to get access to remove the axle tube. Once I did, I found the bolt broken off flush with the CI housing. I tried drilling and using an EZ out, but it would have taken a trip to the store for a better bit or a few days of drilling. Anyway, the hole I started was off center, so I took a punch to see if I could get it to turn. Low and behold it did. Got a few revolutions and then used a cold chisel to turn it the rest of the way out. Not too bad. What was actually happening was that when the short bolt was tightened it was actually opening a gap between the axle tube and the rear end since it was pressing against the broken stud. Took a closer look at the other side, and have a similar problem with one of the frame bolts there also. So a trip to my local dealer is in order to see if he has a few gaskets for me. Not as bad as it could have been, and hopefully not only will it quit leaking, but be fixed right.
It looked pretty good inside, but there were some areas in the rear that had some thick coagulated hytran. I've read about cleaning out the rear with kerosene or brake kleen, any opinions on which is better? While I'm in there, I may as well clean it up.
