This happens when the inner seal fails and the bearings get washed out with gear oil. From my reading on mud it sounds like the gear oil is a better lubricant than the grease, so as long as it was sufficient quantity should be ok. Not sure about the use of moly on the bearings
I just used regular wheel bearing grease on mine.
