I had a vibration issue with the LeMans once, and it ended up being the yoke on the rear, the 'nubs' that center the u-joint caps were worn, and the u-joint would shift making it 'wobble'. It took a very close visual inspection to catch that.
Keith - What's the source of that diagnosis chart, etc? I'd like to have a copy on hand...
