noisy TRW pump after rebuild

[Dickyj420]

After rebuilding the TRW power steering pump in my 1968 charger with a 383 it makes some noise when cold. it also howls under a load at low RPM's. Has anyone encountered this issue before; nothing looked damaged during the rebuild. I did the work following a you-tube video, and after saw in the comments that 2 of the fins might have been installed wrong..... I put all 4 in the same direction like the video, can this be the issue? The video helped a lot, but you never know if it is the right advice. Maybe I bled the air wrong or something; but I do not wanna cause more damage. If the pump is done what pump and brackets should I replace with, matching parts for this car is a nightmare lol? thanks...

Did you bleed the pump by turning the steering lock to lock with the wheels off the ground, engine running?

No Sir, I will do this later this week and let you know if it fixes my issue. Thank for your time here!

What fluid did you pour in the system? Did you flush the box?

There is a right and wrong way of putting those vanes in. One edge has a chamfer, and the other does not. Consult a Factory Service Manual. I have had a lot of trouble with my TRW pump on my '64 Polara. I suspect my rebuilder may have installed the vanes improperly in my pump. I have very little assist at low speeds.
