never done that though.  I only use 4wd to keep from fishtailing, loosing traction, hitting other cars, etc., when it rains.

It sounds to me like it is internal. If it only vibrates in 4hi and not 4low, then it is a gear that maybe have a chipped tooth, could be from those shifts from 2wd to 4wd. Take it in, it is under warranty.

only lifetime if you have EVERY service done at the dealer.  I am not paying $400 for them to check a bunch of stuff and only do $40 worth of actual labor.

Check your owners manual on servicing. Find out what the service interval is on the t case and xmsn. If you havent hit that mileage yet, you should be covered for a look see. If you have passed it, and you had changed the fluids at that time, hopefully you kept the recept from when you bought the stuff. I dont know how the dealership in your area works, but here, if I show proof that I bought the stuff, and I marked it down on that servicing card that came with the truck, I am good. In the back of the manual, it reads that if you have the ability to do your own servicing, you are authorized.

Notice the middle picture in the last row.... is that driveline angle ok?  Seems pretty sharp to me.  The 2nd pic shows what happened when my running boards were ripped off from the accident, the first pic shows what it should look like.

I had the Hemi in the Jeep.  It drove me absolutely nuts!  I would kick it into manual shift cause that over rides the MDS so the tick went away.

Supposedly mine has the MDS, and I have NEVER seen the benefit of it.  I have gone from VA-TN 5 times, VA-IA 3 times, and numerous other trips over 500 miles.  The BEST, using cruise control at 65, mpg I have ever seen was 17.  Its normally 15-16 on long trips.

Hemi sucks....

My jeep used to have the same issues. I ignored it (i was a teenager) and ended up having my T-case basically explode.
In a related story, after my T-case was replaced I ignored my transmission leaking and kept it full of fluid and checked it regularly. One day on the freeway 5th gear decided to give up on life and grenade, perfing my transmission and leaving me a loooong way from home.
Those 2 fixes cost me about 3 grand and that was with cheap labor as I knew the owner of the shop I took it to.

Moral of the story? Take it to the dealership and explain what's going on and see if you will be covered. If not, spend the few hundred bucks to find out the actual cause of the issue and fix it. You'll save a crap-ton of cash in the long run. :up:

(( My jeep still runs with over 220k miles on it and over the course of it's life has had these parts replaced: both axles, both driveshafts, 2x T-case, 1 Transmission, and 3 or 4 fresh installs of  carpet in it, none for upgrades, all because I trashed the stockers LOL ))
