    Lay under the truck and rotate the driveshaft by hand. Listen/look for the clank location.

    Throw it in neutral and also rotate the dirveshaft at the back of the tcase, check for excessive play. Not sure what kind of truck it is though. Sounds like a ujoint.

    Might be safe to just change out yer ujoints, Ive had them be completely tight, no play but make noise and be totally screwed. Check yer pinion nut, I have seen those come loose and make make noise
