Re: Dana 60 too much?
The weak link in most cases is the axle shafts.
Even in a Full Floater 60 the 30 spline shaft is no beefier than a D44.
It is a Full Floater, so the shaft only has to transmit torque to the wheels it does not have to carry the weight of the vehicle. So it is inherently a little stronger than the D44.
If you are running a locker, breaking a shaft doesn't leave you on the side of the trail, and it is so much easier to swap a broken shaft in a FF axle.
Heavier = more unsprung weight
More expensive to build or fix
Harder to find parts for in the middle of BFE
Less ground clearence.
(Yes you can grind it, but you can also grind a D44)
Most are a lot wider than the companion front axle you will likely run. So you will have to narrow it.
= custom shafts
= better have them make you some spares
Personally - Up to 36" or so I'd run a D44.
Now, I am in the minority as I believe SWB Jeeps do what they do best, because they are nimble. If you want to make a 3/4 - 1 ton truck outta your CJ....
Go with the biggest axles you can find/afford.
