Didn't know if any one out there could help me out with this. I scored a Dana 44 rear axle out of an 87 cherokee and called the dealer with the VIN. They stated that the gearing was a 3:42. I want 4:10's. I have someone here locally that has 4:10's out of a Dana 44 rearend from a TJ. I called my local driveline shop and asked if the splines were the same in these models. They came back with the statement that the housing were different due to the gear difference. Saying that because the of the gap between gear sizes, I would need the housing as well, not just the gears. I didn't know that the housings were different at all within the same axle model i.e. Dana 44. Any help would be awesome.

Thank you,

Eric.

i'm not sure about the spline counts in these particular axles, but it sounds more like thier talking about the differential carrier, what you bolt the ring gear to, not the housing you put it into. hope this helps, thats a good score!

The TJ D44 is different from all the rest of the D44s. It is the gears that are different, pinion I believe. You will need a different carrier though. All the Dana axles have two different series of carriers that change somewhere around the 4.0 to 1 range. I think on D44s if I remember correctly it is 3.92 and up takes a different carrier. So, if you want the locker, this is a good time to kill two birds with one stone.

One other thing, if you get just the carrier, the side gears will interchange.

i think the d44's carrier break is up to 3.73 and then 3.93 and up.

yep pretty sure this is right... 3.73's is the lowest gear (highest numbered) you can run in the smaller carrier... i havent seen a jeep with 3.42's or whatever either... but since nobody else objects... i guess they had them... lol

Here's the deal, bro. I went the same route you are going. I put a D44 rear axle out of an 87 XJ into my 91. The factory gearing if the 87 XJ had a 4.0 and an automatic is 3.55. I bolted it right into my 91 with 3.55 gears and it was just that. Bolt in and play.
Now, when it came time to do my gear my gear swap, I went to 4.56s. The guy at 4Wheel Hardware told me the lowest gears with the OEM carrier is 4.10s. Anything lower and you have to buy the more offset carrier, which I had to do.

Whatever dude. I'm not one of those guys who has to be right all the time. Like I said I went to 4.56s and I had to buy the different carriers. That is all I can speak for positive. That was my personal experience.

never said or acted like i needed to be right all the time... what you posted right now makes more sence to say... but what you said before was wrong... and wrong information on a quesiton leads to problems for the one who asking it... so i was making it RIGHT before he listed to what you said and spent all this money only to need to spend more and have his jeep not drivable for some time... its not about always being right... its about what is right and what is not... that is why i posted other threads to back up what i was saying... so i wasnt just talking our of my *** like yourself...

"I went to 4.56s and I had to buy the different carriers. That is all I can speak for positive. That was my personal experience."
