[V8] Power steering leak

[george.fallot@verizon.net]

    Hi, I'm losing power steering fluid. It seems to be leaking from the pump,but I can't see where.The hose connections on top  seem to be dry,but under the pump is wet and the air compressor is also wet.
    Do the seals go bad on these pumps? Is there a way to tell without taking it out? Are they hard to reseal,or do you just get a new (reconditioned) pump?
    By the way, the pump was replaced 5 years ago, about 50kago.
    Thanks,George
