Dana 30

Here‘s the most common cover ever. This shape is for the Dana 23, 25, 27, 30 and, in a slightly larger version, the 53. The 23 and 25 are on the early WWII rear axles, with the 25, 27, and 30 primarily being front axles from WWII to the present. The 53 axle is used on the rear of some pickups.

The AMC corporate Model 20 has 12 bolts and a round cover, which was used in the rear of ‘76-‘86 CJs and a few mid-‘80s full size vehicles. though a few design problems have given this axle a bad reputation, it‘s nevertheless a good unit and very common.

Dana 60

Though larger than a 44, the Dana 60 and 70 share the same cover shape. Jeep used few 70 axles, but quite a few 60-series found their way into the rear of ½-tons and ¾-ton pickups.

The Dana 44 is the second most common cover, used from the late ‘40s to the present. Primarily a rear application, the front of many pickups, FCs, other fullsize Jeeps also received this axle.

Dana 35

The Dana 35 and 35C are used in the rear of many YJ, TJ, XJ, and ZJ Jeeps. Smaller than the 44, the cover is nearly the same as the Chrysler 8¼ axle and nearly indistinguishable from it. This light-duty unit is adequate for most needs, but larger tires can cause the housings to bend and axles to snap.


The preceding data was taken from "Axle ID Guide" an article found in the November 1999 issue of Jp Magazine.
