Looking for Shawn (shk) Vibration help!

[Dave_Vrba@mail.sel.sony.com (Dave Vrba)]

     Sorry to blast the list.  I was looking in the archive "vibration" and 
     got back data from Shawn shk@qnet.net.  Sent him a E-mail but came 
     back undeliverable.  Shawn ! You out there?
     
     I got a vibration similar to what you had back in your Sept '98 
     posting and want to know what you found was the problem.
     
     My vibration just started yesterday.  Very quick vibration occurs at 
     around 35 MPH to 55 MPH.  Shakes the rear view so you can't see out of 
     it.
