Re: Driveline Vibration
What about the transmission? Could anything in the trans rebuild be the root of the problem?
I've got a similar problem. Just a slight vibration between 40-42, 50-52. It's barely enough to feel and make the mirror shake, but it's there. In my case, the engine was rebuilt, but the trans was so far gone that it was hard to drive at all much less feel any vibration. Trans got rebuilt and everything runs well, except for the slight vibration.
I haven't lowered it, I haven't gotten the driveline balanced, and I haven't checked the carrier bearing. My first thought is now that I have all this new HP hooking up to the driveline it's showing some wear in the CB and now it's possible to notice some imbalance in the driveshaft.
But I did notice it after the tranny rebuild...And you have a rebuilt trans as well...
