I started having these vibrations - body of car, not steering wheel or brake pedal - when applying power at certain speeds. They spread to other speeds over the course of a few months, and in the last week (with driveshaft) increased exponentially and became so bad that I thought it best not to drive the van. Removed the driveshaft, presto - problem gone. The u-joints were in sorry shape - binding and sticking - so I had them rebuilt by a local driveline shop. Reinstalled the driveshaft - the vibrations weren't quite as severe, but were still completely unacceptable - driving the van still didn't seem like a good idea. Took the driveshaft back - he rebalanced it - no difference. He said "there's no way just a bad driveshaft could be causing vibration like that". My door lock buttons were unscrewing all by themselves! The front bearings and outer CV joints check out fine, the inner CV's were both replaced about 10-20,000 miles ago. Aarrgh! Where's the problem? Still the driveshaft? Front end of drivetrain? Transmission? I don't have the wherewithal to begin tearing apart the drivetrain to figure out which bearing is shot, or otherwise what the problem is. I am hesitant to go to my local VW dealer because of a) price and b) previous less-than-satisfactory experiences. There are a few VW specialists around - they seem to be air-cooled specialists - "Syncro - Oh - I've seen a few of those around...". I've heard a lot of good things about some transmission people on the list, but none in Northern New England that I can recall. I've got family in NJ and could conceivably go to Ken W if he's comfortable with this sort of stuff, but I wish there was someone up here I could feel confident about! Any ideas, fellow listees/syncronauts? Doug Fitz-Randolph Yarmouth, ME (Southern Maine) dfrandolph@talkam.net '90 Syncro (145K on odometer, 50K on engine, 70K on trans)
