JK differences

Hi all,
JK 2.8 CRD Sport 2011,
how do I recognize a front axle dana 186 MM with 3.21,the one with 3.73?
there is a part number on the front axle ?
or by ring and pinion ?
thank you

Giacomo

I would look at the dealer build sheet if you have it. It will identify the stock configuration on the left listing and any options (that over ride the stock configuration) on the right column.

No indication of gear ratio on the outside of the axle here in the U.S.

I don't know if they put a tag on the export models.
