Wondering if anyone could point me in the right direction. My truck has a clunk when accelerating, never happens from a dead stop just when coasting on the road then applying the gas. It happens in 4wd. The transmission does not seem to be slipping and i have greased all slip joints. All u joints seem to be in great shape. Anyone have ideas what to check next.

 

Well...the front diff has some mounts

.... maybe control arm bushings

....or maybe transmission mount but that seems like a long shot. Maybe a stretched chain in t-case but that's really grasping at straws.
