Description
Rubicon JLs come with the M210 front axle and the M220 rear. If you don't have a Rubicon, then you have the M186 front and either the M220 or M200 rear. The M220 is the axle that comes with non-Rubicon Wranglers that are equipped with the limited-slip differential (LSD) option from the factory. Review your factory build sheet if you're unsure.
