K well I got home about 5 mins ago and I said to myself hey, i havnt tried my 4wd ever since I fixed the hubs. So I was like hey I wont go far so I pulled up about 3-4 feet. I stopped and for some reason I wanted to put the tcase into N cause I dont know what it does in nuetral and figured now would be a good time to find out. As soon as I move the lever the truck lets out a metal scream . Now after the scream i try to bring it back to 4 hi and same thing, more noise. I had to shut the truck off, put tcase into 2wd and turn it back on to make sure evrything is ok. I almost pooed myself , anyway anyone know what just happend to me or am I going to have to go over my whole 4wd system before I use it again?
