2004 Saab 9-3 ARC w/230,000 miles.

Steering starting to act funny. Hard to describe, but mostly does not seem to want to return to center on it's own and is tight turning, but only at the start of the turn and then seems ok. comes and goes.

I've been told it is the steering rack going bad, since there is no noise coming from the steering pump.

Fluid was just an ounce or two low, but well within the lines.

Any opinions?

Thanks in Advance.
