Power steering pump problem. Possibly low fluid getting aerated at high RPM?

Is it hydroboost? Perhaps you lost the belt.

Or - broke the pully off the power steering pump. Don't ask how I know that one.

K3500 with a 454, I'd say it's hydroboost. I'm @$$uming, since he refers to a long drive at highway speeds that it works normally otherwise.

I'd also guess it's not too big a problem since he hasn't responded.

Does the pump have hydraulic fluid or transmission fluid in it?

I put the lucas power steering fluid in it but I think I still might have trans fluid in the system, yes hydroboost too.
