Another Bad Vibration Thread

[JDwhite98gt]

So posted on here the other day about my clutch change. Well its been about 150 miles and the chatter is still there but ohwell....theres no way im doing the tranny again in this weather. So last night I said screw it and wanted to rip it so from second gear on it was full throttle. By the time I hit top of fourth the car felt like it was going to vibrate into pieces. I had just changed the u-joints an hour before and I replaced a cracked rim. The vibration is felt everywhere except for the steering wheel , so most likely drivetrain related. I had also found that the driveshat bolts had backed out so maybe need to put some locktite on them? I know motor mounts and tranny mounts should be checked but this vibration is B-A-D! and only top of fourth at about 80mph +. What else should I look for?

i had the same problem and my driveshaft was un-balanced... now its much better.

did you install the drive shaft in the same position it as in ie hole 1 with hole 1??? sometimes it can be indexed wrong ( see it mostly with a slip joint on the back but can still happen with our style Driveshafts. Or it could be completely unrelated and you could have lost a wheel weight.
