I've had my WJ for a couple years now. Nothing too crazy, but I've always wondered about the difference between the D44 and D44A. I posted this in another forum, so please don't flame me. I haven't found a concrete answer to this anywhere.
I know we've all dreamed of having an iron Dana 44 in our WJ's instead of the aluminum Dana 44A, so we can have more locker options, easier parts finding, etc. But has anyone actually tried to install iron dana 44 parts into a dana 44A, assuming they're both 30 spline shafts? I'm curious as to what parts exactly don't work in the 44A from the 44. If I knew how to rebuild a diff, I would try it myself. Anyone know for sure? Hypothetical, maybe say D44 ring, pinion, carrier, etc. from a 2003 TJ Rubi into a 2003 WJ D44A.
I've never heard of anyone trying it, but I think it'd be a great thing for the ZJ/WJ world if it was easy to do since that would open up a lot of options. Hopefully someone who has setup both types of axles will be able to chime in if there are obvious differences preventing it from being possible.
You might want to talk to Carl Jantz at Jantz Engineering. He has a lot of experience with getting dana parts from different axles working together. He's done the Jana 76 (D70 gears into a D60), Jana 54 (Dana 50 gears into a D44), Jana k4 (JK D44 gears into a regular D44). I haven't heard of him trying anything with the 44A. That said, I have no personal experience with his kits, but I'm just mentioning his name since he'd probably "the" guy to talk to if it hasn't been attempted. His screen name is unRL at pirate.

I don't even think any of the parts are the same dimensions other than overall width are they? If it were possible someone would have figured it out by now. And why even go through the trouble and still be left with the aluminum housing when it would be far easier to just swap in an 8.8?
A guy on JF had his existing D44a tubes pressed into an Iron D44 center section. As far as the internals of the diff go, they're different. I believe someone on MC took a D44 spool and machined it to work in a D44a a while ago though.
This is my first post on here and i have to ask are you all dumb asss , the d44a is a heavy duty 44 dana 60 size pinion and thicker ring gear that said that said the housing is the weak link. If anything was swapped it would be 44a ring and pinion in a reg 44
No problem planetcat was not directed to you but maybe the others that posted and did not inform you about the d44a
