Default Steering Hissing noise - Pump or Rack?

The steering on the '93 makes a fairly loud hydraulic hissing noise when I turn the wheel at low speeds (or parked). It'* not deafening or anything, but it'* far more noticeable than it is on my '96 or was on my '89.

Is that a steering rack going bad, or a pump? Or just noisy and not necessarily bad?

I'm going to have to replace an inner tie rod anyway, so if I'm going to need a whole new rack, it would be really nice to know that now, rather than afterwards.

To answer the first question you'll ask, I have plenty of fluid in the res.
I'm Jon. I'm completely stock, no mods.
1993 Bonneville SSE 191,000 miles "The Work Beater" Imperfect but quite tolerable. Stock.
1996 Buick LeSabre Limited, 181,000 miles "The family car" Custom CAI, F41 Sways.
Sold/dead, but not forgotten: 1989 Bonneville LE "Bonnie, the Sport Utility Car" STB from '92-'99 Bonnie, Delco (Type II) Ignition system
