1990 Super Duty problem

I have a 1990 Super Duty w/ diesel engine. It has the power steering pump that also runs the brake booster. The power steering pump growls and fluid foams out of the cap. It doesn't appear to have any leaks and the fluid is full after the foaming settles down. It used to work Ok and just started doing this. Any ideas? Thanks
