First, Howdy. Long time lurker, registered today, first post.
I currently own a Bronco II. After playing with full size Broncos for a couple of decades, decided to downsize. Was looking for Cherokee when the BII popped up on C/L as a roller. It's a 2.3L, TK5, BW 1350, with a '91 Explorer front, '03 Explorer Sport Trac rear.
I did an extensive post over at Fordsix.

It's mostly a trail vehicle. I want to ditch the Dana 35 TTB for something stronger. Have looked at the Dana 44 knuckle swap, the various SAS options, but I think my best course is swapping a Dana 44 TTB from a half ton. This will widen the front a bit to match the wider Explorer rear.
The four cylinder needs all the help it can get, so I think I'm going straight from 3.73:1 gears to 5.13:1 gears. Those with 33 inch tall tires should be about right.
Problems:
Dana 44 carrier break. To fit a 5.13 gear in a Dana 44 housing requires a 3.92-up carrier. I've never seen one.
Dana 50 center chunks supposedly swap in, and don't have carrier breaks.
If I use a Dana 50 center section, might as well use the bigger passenger side shaft/joints, since I have to alter a Dana 50 middle shaft to swap in the Dana 44 right axle.
Or just buy a locker for the front to ditch the stock Dana 44 carrier.
Comments? Any problems/tips for what I'm thinking?
