Thanks for the thread Romer. I've been hearing the whinning for awhile and it seems to stay with me accelerating longer and longer.
Now that I know it is in the transfer case, I have some real soul searching to do. I guess I need to get it down to Christo and company to get it fix so that I can turn another 200K on it. Problem is I kinda need a ride to work...
So now I have to add that to my list of things to have done.
