So I want guys who know what there talking about here not hunches not to be rude but got a lot of building in short time frame for a Mudd run Lol

So first what's the difference between standard and auto transfer cases and can I make the standard one work with my auto case that's no good

OK second what's the issue if I put a 4.9 gearing in the front of my x as I've done a lot of damage to my 4.6 diff and can't find one I got a month to build and limited funds so let's see if we can get me on the right path :)

Not gonna happen.

Yes. You can jack up both rear tires and put it in neutral and spin the rear drive shaft and count how many revolutions the tires spin to one full revolution of the drive shaft. That will give you the ratio. If you have 4.6 then it'll look like 4 and a half spins and if it's 4.9 then it'll look like 5.

A 4.6 gearing will spin the tires 4.6 times to one drive shaft revolution.

4.9 is 4.9 times.
