Axles. Without em, a Jeep would be dead in the water. Were talking complete axle assemblies of course: what you put gears into, tires on, and a place to hook your suspension and drivelines to. Theyre pretty darn important, but many Jeep owners are clueless about whats under their Jeep and dont have a reference that will explain it all.
To that end, weve come up with this quick-n-easy Axle ID Guide to help you spot whats underneath. We wont go into all of the intricate details, since each axle model is almost a story in itself. Instead, we recommend that you use this guide as an overview, and the next time someone asks you Watcha got under there?, you can answer with authority.
Most Jeep axles are produced by Dana Spicer, one axle was made by AMC, and a few were produced by Chrysler. The Dana axles have been available in front and rear versions, with many varieties of each. The easiest way to make a quick ID is the shape of the cover and the amount of bolts holding it on. The actual inside ratio and axle spline differences are more difficult to ascertain without looking inside, and even the little metal tag on the cover bolt isnt a solid indication of the truth.
So, check out the photos and get a clue about whats underneath your Jeep.
