If you went where the JKX was and where I just got back from wheeling I will guarantee your D30 will break with a locker, 37's and 4.88's.
Well, I don't know if I would "guarantee" it but, the odds of it would be up there especially if you tried doing all the obstacles. What I would guarantee is that the axle would be totally bent by the end of the week. Still, you can drive just fine with a bent housing... well, so long as it isn't too bad. :crazyeyes:
What I will say is that like always, all the guys from the east coast all came confident that they've wheel on hard terrain but after day 1, were quick to remark at just how tough the wheeling really is out here.
