The power steering seems noisy and I don't see any leaks, any ideas ?

I also have a similar problem, only seems to happen for the first 10 minutes of driving...anyone has any thoughts on this ?

Its prob not the power steering...I took mine in for the same thing or so I thought....Its the whine of some type of evacuation pump.

That's true, it does seem to go away after a while

I would check your power steering oil level......could be low??

manual has nothing in it about steering fluid that I could see and I didn't see anything in the engine compartment. Anyone know where it's located ?

look at the driver side intake tube. the power steering reservor touches the intake tube. can't miss it.

I finally figured out what the bad "belt/pulley" sound problem was that I had. On cold start ups, I would get nasty kinda belt slip/kinda mechanical sounds until the car warmed up (~10 minutes).

Finally, I just shot the idler between the passenger side pulley and the power steering pump/ABC pump pulley with WD40 - instant silence. Pulleys might be different on my CL55, but IMC I think the belt runs are the same. This idler I speak of is small and very near the power steering/ABC pump on my car, so I was thinking at one point it could be the pump.

The technician actually reseated the pump to get the belt to line up, the noise was caused by the fact that the belt wasn't riding true on the idler and pulleys.

is it bad or those belts to spray wd-40 on them?

don't spray it right on the belt, you spray it on the bolt/center of the pulley.
