I can't seem to shift the T-case on the fly anymore??? I just replaced all my u-joints and front and ball kit in the front u-joint. But I am not sure why I have to be at a full stop to shift into 4wd???

that doesn't sound good.
you should only have to do that when going into bo low

Went and ordered the Chrysler 2001 Dodge Ram service manual. It should cover everything and I will have to tear it apart and fix it I think it might be the synchro mechanism. I went for a long drive today and I noticed a lot of vibration at highway speeds as well I think I might be looking at my clutch and rear u-joints at the same time and look over the sqawking coming from the drivers side axle shaft (u-joint). Everything seems to be hitting me at once....

wouldn't be from driving over that huge boulder at Waiporous jan.29th EH!!!!!!!

No this is recent. I checked my diffs after the outting and found water in the front diff as always but the rear diff fluid was good until last week when I was changing the fluid in the tranny. I checked the rear diff to find the fluid BLACK as hell and full of metal. When I drained the cover I found a big chunk of metal stuck to the magnet on the bottom of the diff and metal paste everywhere. It worked out perfect as the spider gear that was missing a tooth was looking right at me.
