I just bought my first 4x4 and I was in my driveway the other day shifting the t-case. I think anything I could have possibly done wrong, I did /forums/images/graemlins/1zhelp.gif I had the truck running, and I got a couple of good grinds out of it, and at one point I threw it into park and got some interesting noises too. Any pointers would be helpful. Also, is it bad to drive around w/ the hubs locked? Say I was in a situation where I wasnt sure if I'd need the 4wd so I locked the hubs in case, so I could just shift the case if necessary. I dont plan to do this while I'm cruising around on the roads or anything...just in potential situations.
