Had a locked Dana 44 in my Ramcharger. Had a lot more power than an X can make and the axle just took it and then some.

Oddly, in my friend's Grand Waggy, which he's sunk a bunch of money fixing or modding everything, the front axle is the only thing that hasn't gone out.

Watching this thread really makes me keep an eye out for one to put in the X. It'll be a reaaaallllyyy long-term project, though...
