So I finally made it under my jeep today to check a few things out so I can start my mod planning. I checked the tags on the diff covers and come to find that they have different tags. The front says 3.72 and the rear says 4.11, neither of which came stock on a jeep I believe. 4x4 works perfect, I use it just about every day so I don't believe they are really different gears. So is there a way to know what gears I have without pulling the covers and counting? And how do I tell what axels I have and if someone has switched out the whole thing?
Here is the front tag
And here is the rear
