Terrible bouncing/vibration at ALL speeds in 2wd and 4wd

1999 F-350 DRW Crew Cab Long bed. 4" lift on 37's.
- New tranny, new ball joints, new hubs.

Truck worked fine in 2wd, put it in 4wd for the first time and it jumps all over the place. Literally the entire truck, even at 5 mph each corner of the truck is hoping/vibrating at least 2 - 3 inches.

Changed it back to 2wd and it still does the same thing!

I crawled under the truck and the Carrier Bearing moves a good inch in each direction, but would that cause the truck to jump around even at idle speed? It does have the drop bracket to compensate for the lift. I read where people feel their carrier bearing going out at 50 mph...I can't go 10mph without feeling like I'm hurting the truck.

Also, I think my axle u-joints are gone because its "catching" my wheel and pulling my steering from side to side.

Last theory is that is it possible that the rear end blew up for some reason? It drove completely fine in 2wd, I parked it and it snowed like hell that night, put it in 4wd and it started doing what I described.

Overall I feel something is "catching" and causing the truck to stutter and bounce. I literally can't drive the truck because it's so bad.

Any help would be appreciated.

Could be a lot of things. If it were mine I'd check your spacers. I run spacers too, and if they get a little loose things start feeling really nasty. Just my $.02. Could be your u-joints in the front end. If your four wheel drive doesn't kick out, or your hubs aren't releasing, it would feel like that too.

if you took it to a shop to have them look at it, the first thing they would do is put the truck up on a hoist and drive it on the hoist to look for the problem.

get yourself 4 good jack stands and put it in drive with the engine running to see if you can see something moving around or hear noises.
