Okay How many splines does the rear aluminum Dana 44 have? Randy's ring and pinion website lists it as both 30 and 29. Randy's R&P Link
I'm looking for prices on some new gears and now I'm also wondering if the Dana 30 front differential is known as the "short" model? Maybe this is referring to the "Short pinion" I don't know. I know that the 30 in the front end has 27 splines but I've never heard of the "short" version before. If someone could clear this up for me I'd really appreciate it. On randy's website it came up under this address: http://www.ringpinion.com/productdetails.aspx?prodID=3082 I realize that this item # says TJ on the end of it but it came up when I looked under the ZJ Front Differential ring and pinion search.

TJ, XJ, YJ, MJ, and ZJs use a D30 with a short pinion. CJs used a D30 with a long pinion. This is also why you see a TJ part listed for ZJs. They're the same front axle. The axle shaft spline count has nothing to do with it.

I see the confusion on Randy's site about the D44A. I couldn't tell you which is correct off the top of my head. Try a Google search for "D44A spline count" and see what you get.
