Not for 37s, nope (although we do have a member in our club running 37" iroks on his D30, he does break parts, knows its limitations, brings spares, and knows how to work on it).
For 35s, in most stock motor/trans situations, I'd have no problem running a Dana 30 front. Heavy/Big 35s, like a 35x15.5 SX, etc, obviously are again a difference scenario.
