Thread: Mild vibration at speed

Tweet

I will check that, but the universals are both brand new, unless he overtightened them or they are defective, i think there's more of a liklihood the problem is in the balance or straightness of the driveshaft itself than the universals on the ends... I'd imagine its just a longer shaft that was shortened to fit a 32, I'm figuring there's a fair chance it may have been welded crooked, has a slight bend, or something along those lines...I didn't find a tree big enough to do the official driveshaft runout "test" , but I'll start digging into it soon and keep you posted on what i find (or don't find!) Thanks for all the tips. -jb

and if it's howling they probley threw away the inner cardboard tube, I did that one my first driveshaft shortening job, took forever to figure out where that noise was coming from.

I have taken a driveshaft out @ the rear yoke and rotated it 180 degrees and reinstalled it ... and the vibration went away ... more than once ...

I've heard this from someone else too... Sounds like a total long shot to me, but just the same, i plan to try it tomorrow... wish me luck!
