Shaking at 40-50km/h
SO as some may have read, I redid all my U-Joints and support bearing on my 92 Dak 3.9L. It's a 2 piece shaft.
Once I put it back in, I now have a vibration at ONLY the 40-50km/h range.
NO, it's not an RPM issue as I have been at 50km going down a hill or coasting and the whole truck vibrates still.
Is this an unbalanced Drive shaft? I noticed a lighter area where a counter weight MIGHT have been before but is now gone.
The good news is that when I shift, I no longer get a BANG/THUD sound. Also, it goes like stink now.

It could be... It has happened to me before, guess I knocked the stupid thing off not being careful with the shaft. Took it and got it balanced, and all was well. You may have to search for a place that balances them, they aren't on every corner.
