My 1991 W124 has suddenly developed a loud sqeaking sound (not squealing)when I turn the steering wheel. The noise appears to be coming from the front end of the vehicle, rather than inside the cabin. Can any offer any advice on what the problem can be? Or offer suggestions on what else I can do to confirm the source of the noise.

I checked the steering fuild level and it looks OK.

Thanks in advance for any feedback.
