Here is the deal. I am trying to find out what is causing the vibration demon I have been chasing for a month now.

I want to drop the rear drive shaft, lock my hubs and put the t-case in 4hi and drive 2-3 blocks to see if my vibration stops. I only need to achieve 20mph to see if it disappears.

I'm tired of wasting time chasing the problem. The parts I have replaced so far were needed so it hasn't been a waste of money, but it's now to the point that If I just start throwing parts at it will be a waste of time & money.
