Jeep Axle: Dana 25
It 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 alos
much wider than the CJ version.
