Sounds like your cad didnt disengage and the vibes are probably from the unbalanced drive-shaft turning all the time. To test this out jack up the passenger front tire leaving the driver front tire on the ground, do this with the engine running and in nuetral and t-case in 2wd. you should be able to turn the passenger front tire freely, if not you are in 4wd and it is a problem with your linkage. If you are able to turn the tire freely look at the front drive shaft it should not spin with the tire, if it does spin that means your cad in stuck in the locked position and that should be your problem.
Your front axle is a two peice axle and is unlocked in 2wd alowing the tires to spin without the gears and driveshaft turning. It is controlled by a vacuum actuated cad that slides a fork over to lock the axle together when you put the tcas in 4wd. Im guessing this fork was damaged and isnt allowing the axle to unlock.
Id pop open the cad and take a look to see if the fork can move freely.
