    if the bolts were loose the transfer would have been tweeking on the frame when ever you got on it.

    well here's the deal... the bolts were tight and this happened on the right side of the frame, not the left, so i dont think it was from engine torque... do you think it could be from flexing??? my truck has pretty good flex and i had it out about a week ago.... just noticed it now though, not sure how long its been that way... any ideas are welcome, and thanks in advance

    if your frame gets really tweeked,such as up on three wheels and still going farther than that it puts a lot of stress on every crossmember along the frame.the crossmembers are twisting every time one end is up higher than the other.like doing a lot of rockcrawling would probably do this becaude the frame is getting twisted on every rock.and to add to this it is being twisted by the torqe of the engine and drivetrain spinning.i would say that was probably your problem.your frame has been twisted so much the stress between the crossmember pulling on either side of the frame finally cracked it.i would say get a thicker brace than the stock frame and also check the rest of your crossmembers where they attach to the frame.

    that makes sense... i did get pretty twisted up that day showing up all the tj's i was wheeling with... they were pretty darn impressed when i flexed on a 4 foot rock and only lifted the right rear about 6 inches... didn't even think about that...ill check the rest though... thanks /forums/images/icons/smirk.gif
