I had a recent failure in my driveline. Long story short, the rear driveshaft came loose and the vibration broke the piece between the transmission and the transfer case. My first question is what is this piece called and where can I get one? I have a 1990 bronco with E4OD and a Borg Warner 1356. Secondly, the transmission was leaking fluid like crazy out of the rear seal, I plan to remove the transmission myself (Ive done it before so Im not worried about that) and have it fixed at a shop. So to the tranny pros out there how much work is required to fix this rear seal, and what is the potential for further internal damage that I can not see? Thanks for any input on the situation.
