Rear main seal has been leaking since I got it. One piece seal so a little more difficult to fix.
Other engine gasket leaks, but nothing unexpected of a vehicle with 200k+ on it.
Numerous electrical shorts, but mainly due to the dirty engine compartment and wheeling mishaps.
Be prepared to put a little money and work into a BII, but it'll go forever.
Acts just like any other Ford, does nothing spectacular but everything well. Pulls my boat, can 4wheel very well for a pretty much stock vehicle, did a 130 mile commute daily for a semester of school with no problems but the alternator.
Not big enough for me though. Seats aren't very comfortable and there's not enough headroom. Other than that she's great. 100% original after 206k.
One piece rear main seals are easier to fix than two pice seals. Just drop the transmission and lightly tap the new seal in with a hammer. A two piece will require you to lift the motor up and drop the oil pan, then you have to mess with the oil pan seals.
I have a 1988 Bronco II as well as some friends of mine.
We have all found that the transmission does slip. I thought I was going to have to buy a new tranny, but if you keep the transmission fluid full to the brim, the slipping stops.
