Re: 14 bolt dually diff ,04 has no front pinion bearing

Negatory. The newer 14 bolts went to an 11.5 gear and lost the pinion support bearing. (I assume the pinion support is what your talking about. They changed somewhere around 01. The strength between the 10.5 and 11.5 14 bolts is supposed be about the same.
