Squealing Steering Wheel
 

On my 1987 190E 2.3, it makes a squealing noise when turning the steering wheel either left or right. Power steering fluid is at proper level. I checked the noise is not coming from the power steering pump and is isolated inside the car (steering wheel).

Any idea what this is or will this become a big $ problem?

I have the same problem on my 2001 E320.
Any ideas what could be wrong?

surprise: turning steering wheel
 

I have the same problem. When I turn the steering from the center position I hear a noise or groan through the first 15 degrees of movement with a turn to the right or left. This sound is not made with bumps allong the road. I believe this sound is not heard after 15 miles per hour. Any thoughts?

i remember hearing about a steering belt that could be frayed. ill try to look up more information on it. search here and on mbworld.org and benzworld.org for more info

I have a 220 c with 100000 miles. This problem feels more mechanical.

I am not sure you are all describing the same problem. I can tell you that a "groan" is a classic symptom of low PS fluid. My C230 had the "groan" so I checked the PS level and it was technically OK. But I added a little more anyway and the groan went away. I also have a light "chirping" sound that occurs whenever I turn the wheel to the right while I am driving slowly. I really thought it was something in the steering wheel, but it turns out it is the heater fan that gets moved a certain way the the cars pulls to the right, causing the fan to "chirp".

Use real power steering fluid and not tranny fluid.....that should help as well.

Change power steering filter as well.

i had a noisy steering wheel problem once before. then i found that after shifting the steering column in a little bit the noise was gone... :blank:
