Yes I have read this post and from what I can see I have no discernable wear on the splines and the are engaged most of the way. The part that intrigues me is the part about having the rear of the transfer case off and getting a new bushing installed. I am wondering if this is my issue. I just had the driveshaft balanced and the vibes are less but they are still pronounced. I am hoping to go to Vancouver next week, but with the vibes I am having I don't want to take it. It would be real nice if one of you could go out under your paj and push up and down on your driveshaft where it enters the transfer case. I get about 1/16th of an inch up and down and side to side play before the transfer case starts to move. Is this normal or to much movement?
