TRW ps pump question

thanks 4spdragtop for this thread and all the photos/videos!

I have a trw pump that is leaking at high speeds. Also noticed the shaft is moving in and out when belt speed is increased and wondered if this was normal. - see that it is not after reviewing your thread. Thanks for posting your findings.
I am still trying to wrap my head around all the parts and how they work/go together. Will study the post in depth and may be trying my hand at rebuilding all the way down to replacing the bearings.
I am somewhat mechanically inclined (it usually takes me three tries to get it almost right -lol) and I am up for a mild challenge but have limited tooling (no press, etc) so need to figure out if I should attempt doing it myself if I will be better off trying to find a good rebuilder or someone who has a good pump available.
