| The
D25 came with three different styles of axle shaft joints,
the Cardan-Cross style being the best.
Military
vehicles with the Dana 25 include the MB, M38, M38A1,
and M170. CJs with the Dana 25 include the CJ-2A,
CJ-3A, CJ-3B, CJ-5, CJ-5A, CJ-6, and CJ-6A. The Willys
Wagon and Willys Pickup used the Dana 25, but obviously
the two wheel drive Wagons and Pickups did not use
it.
The
CJs used a small drum brake around 9" in diamber.
The Willys Wagons and Willys Pickup used larger brakes
(11"x2"). The Willys Wagon and Willys Pickup
version is also much wider than the CJ version.

| Many
parts of the Dana 27 interchange with the Dana 25.
The Dana 27 normally came with the superior Cardan-Cross
u-joint type axle shafts, but carrier bearing and
ring and pinion are smaller than the Dana 25.
The
CJ models that used the Dana 27 include the CJ-5,
CJ-5A, CJ-6, and CJ-6A. I have heard rumors that
M38A1s were always built with the Dana 25, but I
have not been able to confirm this.
