Has anyone had this problem? For the last couple of months I have noticed that my steering wheel on my '93 400E (130 k miles) makes a "creaking" sound if I apply any fore and aft pressure on it. For example, if I hold the wheel at the 12 o'clock position and move my hand foreward and backward, I'll get the noise. This is NOT the creaking others have described in the front end from bad ball joints; what I'm talking about happens at rest and seems to be clearly coming from the steering wheel and/or column itself.

FWIW, I do have a telescoping steering wheel. That mechanism seems to be working fine, and the creaking sound happens regardless of how far in or out the wheel is telescoped.

I'd appreciate any thoughts and experience anyone may have had on this.
Thanks!
