Dd you get it figured out? I have been having front end vibration for months now and can not find it. I have changed the pinion angle countless times. Put new u joints and centering ball in the front shaft. If you remove the front shaft it goes away. I may have the balance checked on it next.

This should be your next step. If that doesn't fix it consider bent output shaft on the TC.

It was just way out of balance. Having the drive line shop balance it took most of my vibrations out. I know there is still a little in the rear drive shaft but its not that noticeable and the pinion angle looks good as well as the ujoints so I'm not going to worry about it right now.

At what point will you start worrying about it? When the u-joints wear out? When the drive shaft comes apart? When the seals on the transfer case or pinion start leaking? Rotating parts don't like vibration and they will find a way to make their displeasure known.

Keep in mind that free advice can frequently be worth less than you pay for it.

This.

Killed my front pinion seal and bearing by running too long with a vibration in the front.
