Front Drive shaft replace -- heavy vibration over 60

I've recently had my front driveshaft replaced to stop the chain dragging sounds from the rear joint on the shaft being worn out. Now I am getting a heavy vibration that gets progressively worse with speed once I hit 60mph. I took it back to the shop and had them replace it with yet another driveshaft but still the same issue. Actually somehow its worse. I was hoping the driveshaft wasn't balance or something but now I have no idea. They did drive it without the shaft and it had no issues. The previous shaft didn't have that vibration either.

Any ideas? Other than replacing the driveshaft again? I'm ready to just take it out completely and not have 4x4.

I'd first suspect wheel balance.

But if you remove the front driveshaft and the vibration goes away, you've fount the problem.

If they replaced it with a used shaft, it could be bent or bowed... :idea:

Both shafts were new. They put one on, found the vibration, then warranty exchanged for another one, and it actually got a little worse. I'm thinking about just removing the front shaft, and then trying to fix the busted joint on the old one. I've got one of the replacement kits but its gonna be a pain.

I'm just trying to figure out why the old one would be fine but 2 different new ones are having issues. Its a pain in the booty. I try to get something fixed but now its worse.

Are you sure the ones they are installing are for your vehicle?
What is your year & model and is it a diesel?
