I've had this Cherokee for over 6 years now. As far as I can tell from my research, I have a Chrysler 8.25 rear axle. Turns out, when I got parts for my axle, the 8.25 was not an axle option for the year of my Cherokee.(89) I bought axle seals for an 8.25, but they are not the same as what's in my axle. My parts supplier and i are having a hard time figuring out what axle it is. I gave them the number off the axle seal that is in my axle to try to figure out what axle it is, all they can find is from a 90s Dakota. It has a Chrysler symbol cast in the housing.
I pulled the shafts, and it is 27 splines.
Can someone tell me what it is, and maybe what year?
Oh there are a couple small tags bolted to the cover. 1 says 3.5, the other has a 3044 on it.

 

Looks like an 8.25 to me.

 

If its an 89, its possible its a dana 35... I have an 87 and its orginal is a dana 35, which of course is not the best out there... but mine is doing fine for me now... he's a pictures on diffs.

 

there is 27S and 29S c8.25 you might of been given the 29s seals. I'm just guessing ok

 

another vote for 27-spline 8.25 from a 91-96 XJ

 

bingo

 

According to Quadratec all 8.25's from '91 to '01 take the same seal.

Thanks for the input. I think the 8.25 is the one. The parts person my have given me the wrong seals. Idk.

 

That's a 27 spline 8.25.

That lip on the bottom of the diff cover is a dead giveaway it's an 8.25.

Look a little more after that. See two little humps like rhino horns?

 

I was able to get a number off a seal, and tried to get the parts person to find what vehicals
Take that seal. They came up with early 90s dodge Dakota. Anyone know if they fit with no mods? All the welds and everything look factory. No grinding or old welds.
