For a while now I have had this vibration from 85-105 MPH. From 105-120+ its smooth again.

After I lowered it I had the driveshaft angle all screwed up and had to get a larger degree shim. That fixed the WOT vibration and vibration from 65+. Now the only vibration I have is from 85 to about 110, but faster then 110 it stop vibrating. Not sure how fast the truck actually goes, but it pegs and keeps going... Pretty cool for a CCSB :lol:

Any ideas? I was thinking maybe the driveshaft needs to be rebalanced but don't really know. Input would be great! I want to fix the problem, but don't want keep buying parts hoping that fixes the issue..

Thanks
 
mine does the same....does have a NICE ring around it where it rubbed on an xmember or pinch weld, idk. But it vibes at 80-100 and then goes away.....but sounds like a got damn plane propeller when its shaking...its pretty bad.
 
If you regularly take it over 100 I'd get it balanced for higher rpm than factory does or have a new shaft built so your's doesn't grenade
