I bought an 07JK and wanted to get new diff covers. I bought it already mofied. Its a wrangler X but I was told it was basically turned into a rubicon and I know the X comes with 35's and the rubicon comes with 44's. Anyway to measure them or tell which size they are?

 

It'll be a Dana 30 in the front, 44 in the rear. Unless It actually is a 35

And if it actually was turned into a "rubicon" then it will be a 44 in the front. Just look at the size of the pumpkin and compare it with the rear 44. That should give you some guide.

 

read this and it will tell you the difference in each diff. and it has pictures!!!!
