On my 94 E320 I have noticed at least 2 occasions within the last month of driving when there is a groaning noise when turning at low speeds. It sounds as if its coming from a steering component near the front wheels (its difficult to tell if its isolated to one side or the other). It has only done this 2 times (that I can remember) in the last 500 miles or so. Any ideas that I should check?

I found in the archives that the PS fluid could be a bit low, I'll take a look and report back.

Thank!
