I think the nuts are necessary. The idea is that they "float" in their housing. I think this is designed to eliminate possible binding by allowing the nuts to move a little bit.
As a previous poster suggests , a socket over the nut is needed to keep from crushing the housing. I used an arbor press, which probably gives a little more control than a vise, although a vise would probably work.
