Driveshaft Vibration

[chriskb3]

While going feeway speeds (55mph+), if i let off the gas to coast i get a pretty bad vibration comming from the drive shaft. I havnt noticed any other vibrations at any other time. Im guess that my U joints are shot since i just replaced my CSB. Thought i'd just run it through here to see if it might be anything else (cheaper) that may be causing the vibrations.

thanks,
Chris

my car also did this. did you use new lock nuts?when i did mine i reused them & one bolt came out & a few of the others loosened up.i replaced all nuts & the one bolt.
it drives fine now.

i used new nuts and bolts on the transmission side but kept the old ones to the diff. ill check that, thanks.
