Hey all,

Replaced my 2 piece DS with a 1 piece Wellbuilt shaft about a week ago. Install was a cake walk!
I'm happy with it, but I have a new vibration. It only happens when I'm going 45-55mph, or when I'm accelerating between 2.5-3k rpm.
Getting tires/wheels balances and aligned in a couple of days just in case (I'm overdue anyhow). I'm thinking it could be trans. mount or an imbalance in the DS? Maybe I just need to rotate the shaft into different positions to see if that fixes it?
If there's any tests I can do, let me know. Been scouring the forums to try and solve this mystery.

 

Update:

Got alignment & balancing all around, and the vibration is less, but not gone.
Next is to look at the motor/transmission mounts and DS, specifically u-joints. They may be brand new but I've heard tell that even new ones can sometimes cause problems/burn up too quick.
Will post more updates as I go along! Still wide open to input and suggestions

 

Bumping, would love to hear from anyone who has done the 1-piece swap

 

Did you remove any shrouds anywhere . If so you may have overlooked a bolt allowing the shroud to flutter and vibrate, sometimes possibly suggesting mechanical issues.

Also, thought i'd ad an idea that came to me about mounting a cheap wireless camers under the car. I bought one that attaches via a very powerful magnet that would make it easy to mount it on the underside of the truck to see even more about your suspension and drive train.
The image on the monitor in the cab can easily be rotated with the controls.
The one I bought was solar powered but can be wired easily to charge from monitor.

 

I'll double check and see that everything is bolted up right under there.
I like the idea of that camera, might have to look into that!

 

Are both U joints installed correctly so that they are aligned with each other?
