I haven't had the pleasure of beating a 4wd bad yet. But I have D60s for mine and the wifes clubcab shortbox powerwagons. Both will be bigblocks. Mine a 4spd and hers in the end a 518 but 727 until than. Than I have a D60 that might find its way under my plow truck. My clubcabs hubs are bad and so is another truck I have.
