hey guys just wondering i have a 98 zj limited 5.9 and when i barley give it throttle the whole truck seems to shake. now the only thing i have noticed is my transfer case mount is cracked at the top and when i get under the truck i can push up on the t case and actually see it move in the mount would this be the cause of my vibration prob? oh and the vibe goes away under heavy acceleration

 

Yes I believe that's the cause of your vibration.

Check the T-case for any damage in that area while you're at it.
