I'm rubbing my magic Jeanie lamp in hopes of a multi-quote feature.. LOL
BTW, even taking the time to cut and paste a multi quoted reply, it only will aloow for one (the last quoted section) to pass through to the board.. Just FYI.. haha

With few exceptions, the 4.0 rangers had a 8.8 rear gear, the 3.0/2.5 had a 7.5. The 8.8 in the rangers was a 28 spline axle. If the 8.8 isn't out of a Ranger it is probably for 31 spline axles. The only Rangers with 31 spline axles were the 99 + 4.56 geared rear ends.
So if the LSD is out of an expo, F150 or Mustang the guts are set up for 31 spline and your axles will not fit.
Sorry if you already knew this no telling what someone knows.
Is there REALLY a huge concern or difference as far as "known" NOT speculative by design theory anyway of failure points between 28-31 spline. Outside of the obvious noted by designs again in theory...
I really would like to do an in-depth article. I only ask because myself? I've never seen anyone tear up either of these options up but then again I would imagine in the extreme sense of things, its not only possible but plausible. I'm a bit hard on my truck sometimes but I don't go out to break it, if it happens it happens and I've done some dumb for sure.
I mean if its more of an advantage of say "bullet" proofing the drivetrain.. ok.. now I get it. But people seem to talk about the subject as though ONLY the 31 spline could handle a blast from a roadside IED and your weak 28 spline would be blah blah blah..
