Two weeks ago I added some power steering fluid because it started whining. This last Monday it started whining horrificly. When I opened the pump it appeared to be foaming, So I dumped more in and it ceased.
The weird part is I can't find a leak,(no drips or wet spots) or was it just purging air from the lines?

Is there some place internally it could leak? Can I use the aftermarket pws leak sealer?

Most of the ML's have had "recalls" on P/S return lines..have you had your car checked for those recalls?

Dealership 40 miles away seems to have all the previous records...should I call them?
Thanks,
Kevin

Yes, they will run a VIN inquiry for any recalls.
