I have this vibration when coming from the rear area and can't seem to pin point it. When at higher speeds it's good, and lower speeds it's good. Just when the train kicks into 3rd I believe, but when it starts and if I give it more gas it's goes away, and if I lay off the throttle it's goes away.
History as of a week ago that's when I bought it.
1.Transfer case had a hole in it, so it could have ran dry, more then likely did. So would a barring, or chain in the tcase cause this?
2. Rear end was almost dry due to seals. Maybe a pinion Barring ?
All of which are tight with no play, and all ujoints are good. Have not popped the rear plate off yet.
Thus truck has the electric trani in it so would a bad battery cause the trani to struggle under load?
Sorry for the thousand question.
