Mine did the same thing after I rebuilt it. When I turned it lock to lock with the engine running (and wheels off the ground) it made a really load groaning noise.

I thought I had jacked up the rebuild so I shut it off and took a break. Came back 30 minutes later, tried it again, and the noise was gone. Its been silent and leak free for over a year now.

I think when there is air in the system the fluid must foam so that even with a full reservoir you still get noise. Letting it sit gets rid of all the foam.
