The Dana 25 uses a 7 3/4" ring and pinion that is only available in
4.27:1, 4.88:1, 5.38:1, and 6.17 ratios. The Dana 25 came with 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. The picture on top is
from a 1950 CJ-3A with the small brakes. The picture below is from a
50s Willys Wagon with the large 11"x2" brakes. The Willys Wagon and
Willys Pickup version is also much wider than the CJ version.
