Sharing my experience w mine as well, seems to be inline w what has been described on this post.
Mine did the same thing, after I regeared from 4.56 to 4.88 w yukons. Dana 44 axles, np241 and nv3550 tranny, Jeep west did the gears, then they changed bearings n u joints in the front as well as the DS, that helped a lot but still there around 60mph, rearview mirror tells u cant see all that good thanks to the vibration.
I read somewhere the tc output bearings to the shafts may need replaced w something that handles higher rpms better but i have not been able to find dose or if is a real thing.
Anyways, if anyone has more info let us know!
