" From: farna@xxxxxxx " " I won't have my TSMs and other books for quite a while, so maybe " someone here can help me out. At highway speeds I get a "droning" " sound in my car. I've converted from torque tube to an open " driveshaft (with a Jag rear axle). I recall seeing a vibration " dampener for either 66 or 67 cars. I'm thinking 67 since that was " the first year of an open driveshaft in the big cars, and I don't " recall the problem iwth the torque tube. I'd like some more info " on this. I don't have a set of tech service bulletins (TSBs), but " the problem and soultion could be listed as early as 65. If " someone has any info on this could they send it my way or post " here? I would be interested in a dampener if someone has one. I " seem to recall one mounting under the car alongside the " driveshaft tunnel, and maybe one in the trunk? Of course I have a " wagon, so the trunk mounted one might not work -- depends on how " it was mounted. my first thought - driveshaft u-joint misalignment. didn't the tt have 'cv' [double] u-joints? ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought
