ha, so i replaced all the important vac lines, disabled the cruise control right off the system, still same problem. had a buddy look at it last night, he has the same truck except its a 2500, and he seems to think its something to do with the transfer case. heres why, when driving in 4wd it rumbles/whines at 30, rumble/whines and vibrates at 35 and 40 vibration goes away a little and 45+ is just crazy. when shifting on the fly from 4wd to 2wd i accelerate, let off gas, shift to 2wd, gas a little then back off and it stays engaged for a minute then when it disengages HARD very hard it feels like a tranny slam then all the noise goes away and drives smooth......
