NP205 Question
I noticed my bushings on the mounts were squeezed out. So I dropped it, put new ones in and reinstalled the transfer case. Now I have an insane rumble out of the front shaft that goes between the transfer case and the C6 transmission where I never had any there before.
I took the shaft to a drive line specialist and he said my angles may be off, and not being an expert myself, I didn't think about they have to be plumb and parallel. I start shimming the back of the case and got rid of about 75% of my rumble. I am like jacking up the rear end, loosening it and moving it a little then running the drive line to see its movement like 20 times.
Is there an easier way than what I am doing? Any reference points I can measure? I am trying to get rid of 100% of it like it was before I messed with the transfer case.
Thanks!

So I jacked around with it today, I ended up shimming the the back of the brackets an inch and an eighth and replaced the bolts with longer ones.
The rumble is almost gone, but I am weary of shimming it anymore, any ideas what my real issue is? This is definitely not a proper fix.
I mean literally there was not a noise or rumble before I dropped my transfer case. I went ahead and replaced all the u-joints on all of the drive-shafts, no change.

Something is either not put back together right or you got the wrong parts. I look at it this way, it wasn't like that before so what has changed? it was taken apart and parts were changed so your problem lies in there somewhere.
