car is at dealer for 3rd time. Power steering whines a bit, more like a groan. Louder when cold. Happens nomatter where wheel is at and if turned either way. PS pump was just rebuilt by dealer and I keep bringing it back. They say it is normal. I say BS. I have an oil leak in front too and they can't find it. How the hell can this be?

I drive a 1989 560SEL, which should be the same, as far as this problem goes. I have no whining noise, so it is not normal, (but you knew that!). Check the belt tension, maybe? A loose belt will make it whine.

I had various leaks and drips from the front of the car also. I cleaned my engine and undercarriage at the self serve car wash, then drove home and crawled around underneath. A clean undercarriage will make it easier to find the location of the leak.
Are you sure it is oil? I suggest you look at: The discharge hose from the suspension pump under the power steering pump, as it makes its way behind the water pump and around the passenger side of the engine. Also, look at the P/S hoses, (I hope the answer is "they are new", as the pump was just replaced and the labor is not much more to replace them in the process.) The transmission cooler lines run up there to the radiator too. Maybe there?
Do any of your fluids go low as you drive? This may help you track this down.
I am a fanatic about leaks too, and I found you really need to be diligent about finding them. The dealership may not care as much as you do about this. Try to find a GOOD independant shop to work with. Good luck!

Has this car been driven much since the power steering work was done? If not, with the reservoir full of fluid and the engine idling, turn the steering wheel back and forth five or six times. If there is air in the system, this will help bleed it. I may not help your case, but it can't hurt to try. I have bled power steering systems on 123 cars in this manner with some success.

Good luck,

Have driven car a few thousand miles so scratch air bubbles. I will find a good mechanic after my extended warranty runs out(today). I appreciate any info.
