Yeah, the axles are the weakest part on this one. You'd probably want to get at least some dana 44's, if not ford 8.8 or 9, or dana 60. It had the weaker ba10/5 tranny the early wranglers had, and it broke, hence the never want another broken tranny of NV4500. It was put in by a shop, as well as a new t-case with it (the new tcase was as cheap as the new input shaft and labor-so...)
What's your price range? Ill be gone for a little bit.
Agree, dont make your own road (unless you own the property).
I wanted the nv4500 so I could do highway speed, and go slow and not have to spin tires (less impact).
Right now, my jeep hasnt been driven much in the last 2 years.
