Noise when steering - PeachParts Mercedes-Benz Forum

Hello,
This morning I was coming out of my garage and as I was turning the steering wheel, heard a loud whining noise whenever I was turning.

The noise continued while I drove, and went away about 10 mins later, but now I am *really* worried that something has gone really bad with the steering mechanism.

Any thoughts on this?

BTW: I'm in Boston so weather is fine right now...So I don't know if it's weather related...

Is the power steering fluid level correct?

I just filled it, by topping it off...But now I'm afraid I may have OVER filled it (i didn't notice the dipstick markers before I just started filling..)

Can I end up damaging the system by overfiling? If so how should I drain the excess?

Thanks...

BTW what causes low pwr steering fluid? I've already gotten the power steering hose clamp recall done...

I suppose you could damage something by overfill but I doubt you did. My guess is as the fluid expands with heat it could cause to much pressure and cause a hose or something to pop off or leak. As far as draining you can use a large turkey baster to suck some out. Be sure and use a new one and thow it out when your done. The contamination thing. If you want to drain it you could probably take the fitting off where it goes into or returns from the steering rack, but I don't know if that's a good idea, as one of the sides at least would be under pressure.

I'm not sure what would case the fluid to be low other than a leak unless it was low from the initial fill, or the people who put the new clamp on didn't top off properly after they fitted the new clamp.

I would use only MB power steering oil part# A 000 989 88 03 16

Thanks! I will be off to the store to buy a turkey baster....

Thanks for your pragmatism Ron.

Ok, the noise went away for one day, and now it is back with a vengeance. The whirring noise is there even when I'm driving straight and of course is loudest when I am turning the steering wheel....

Any thoughts?
