Re: eaton vs. corp 14

To me the eaton was/is antiquaited with the pinion bearing loading system (the stubby bolt on the side of the third member). I had my eaton rebuilt a few years back with a new type locker and the new axles with a higher spline count. The drums are expensive but are still available (raybestos/NAPA) and all the bearings and seals. The only part I believe that is not available is the spider gears.
The 14 bolt has all parts readily available and will fit from 4x4 to 4x4 spring perches. The part that is a problem is the emergency brake brackets(so i have been told) but, you will have to modify some parts to make it work.
As for durability, the eaton is combat tough while the 14 bolt is commercial tough and the Dana 60 (truck rear) is not the one you need back there out of all three.
The front Dana 44 HD is the way to go for durability. The axles are bigger than a standard Dana 44. And by the way, the eaton and 14 bolt have the same OD axle shafts while the Dana 60 is smaller.
Now this is what has been explained to me over the years by repital guys and know way is this a professional statement. Just passing on information, so verify before making any decisions.
