Leaking Power steering fluid?

Where could it be coming from? My tahoe has 205k on it and as far as I know it is the original pump and it is humming like crazy. Bad pump, hose???

it is either the hoses, their o-rings or the big o-ring around the pump where it sits in the reservoir. once you run it dry enough it will always sound bad even when full again. if you find stains on the grounds and the amount it takes to refill it is based on actual time and not just running time I say the big o-ring is the problems.

It is everywhere underneath the front end and I normally only find like a drop on the concrete overnight

then perhaps it is permeating thru the pressure hose.
