Has anyone ever fixed a...

...driveline vibration?

I can not find the problem. Driveshaft is straight. Driveshaft is balanced. New ujoints and lobro joint is good. All clocking is correct. New carrier bearings. Car has very bad vibration from 45up. It has some vibraton at 20. It can be felt on the front carrier if the car idles in gear on a rack. I suspected it could be there but everything checked out ok. What could I have missed?

Thanks

P.S. I am desperate for this now. The car has been on stands for a week and I need the car to drive.

Motor Mounts?

If the driveshaft is fine, check what it's attached to. IE Xfer case, Trans.

I had an intermediate shaft bearing fail on me, but before it did, I had HORRIBLE rear end vibration.

Food for thought.

Everything looks fine there too. I checked the motormounts, they're ok. I checked for play at the tcase, it's tight. I thought maybe an axle, nope, all good. (boot is open but axle is tight) Again, I feel the front carrier bearing shake more than the rear one. Can these things go on crooked? It would seem that they cannot.

Thanks for the input.
