I have a 2-door X with the 6 speed and 3.21 gears. I was talking to a gear guy about installing new gears, and he wanted the information on the tags located somewhere on the differential. I'm at work and can't go look under my JK right now. Does anyone know what he is talking about and where these tags are located?

Thanks for your help.

 

They're normally between 2 of the differential cover bolts, but the JKs don't seem to have them.

 

The tag they are referring to is usually metal and tells them what carrier and gears are installed. But as Renegade said there doesn't seem to be a tag on the JKs. I had a 2005 Nissan Xterra, that I traded in on my Jeep (best thing I ever did) that came with a sticker on the axle housing that had this information. As expected the tag fell off after it's first contact with mud off road.
