I'm trying to find out what size Dana differential I have on my 2007 X. There is no differential lock or any other goodies its just stock. Can someone at least point me in the right direction if they don't know what it would be. Thank you.

Is is a 2 or 4 door, tow or no tow.

 

D30 front / D35 rear (some of the first 07's)
D30 front / D44 rear (all X/Sahara mid 07 and newer)
Rubi D44 front / Rubi D44 rear (Rubi's get their very own special D44, not to be confused with the D44's the rest of us are stuck with...)

what he said. check the build sheet.
on the 07 Xs with the tow packages i got 4.10s

 

Funny, my X came with a D44 rear with LSD and a 3:73 ratio with it's tow package.

 

I think in 08, the ratio for trailer tow package changed from 410 to 373. That's what my 2008 x has ( with tow package and limited slip)

 

most all did especially with tow package

 

thanks for the info, I'm guessing its a dana 30. I'm trying to find the front differential size. I'm looking to get a rock guard. It doesn't have a tow package and its a two door.

 

There is no guessing to it. Look at my first post. All non-Rubicon fronts are Dana 30's. Regardless of year or any other option. You have an 'X', which is not a Rubicon, so...

 

pretty much yes...however some did option a front 44 for their X's, it's possible to have one, but pretty rare
Rider...if your front diff looks smaller than your rear, it's a 30
