For more than 60 years Jeeps have had a variety of axles, and we get letters everyday asking, What axle is in my Jeep? Fortunately, we know what your Jeep should have underneath it, but since axles are so easily converted, changed, and modified, all we can do is tell you what the Jeep came with from the factory. While this chart is pretty danged accurate, remember that there is so much overlap, factory screw-ups, and special orders that even we could be wrong some of the time. Weve also narrowed the axle designation of some Dana axles to make things less confusing. For example, a 44-1 or a 23-3 is simply a 44 or a 23. So here it is: What axle your little Jeep came with, parts available for upgrades, and even some common items to look for when fixing them or buying one.
