hmm... (edit- trying to think how to describe it)
the prop consists of-
a drive flange, with one side facing the diff or gear box. on the other side of the flange is a pair of holes to accept a needle roller bearing, secured on the external side by an internal circlip, and within the bearing is a spigot on the yoke. the yoke has 4 spigots, each going into bearings, 2 on the flange, 2 on the prop body. the other end it the same.
on the body of the prop is a sliding joint, to allow the prop to extend and contract, as the suspension extends and compresses.
the bearing carriers I described are the holes on the prop body at both ends where the needle roller bearings are pressed in.
