any time my truck gets above 35 i get a really bad vibration. i got the tires rebalanced-that wasnt the problem. checked the u joints there all fine. if you have any ideas could you please let me know. thanks

no leveling kit...just running 285/70 R16. the vibration is in the drive line. i just replaced all the u joints. i flushed the tranny and diffs.

well its worse at lower rpm...i could be going 60 in 3rd and it will have a pretty bad shake but when it shifts to over drive it gets even worse...and it only started when i got back from wyoming...it was fine on the highway but when i went to take off at the lite it started getting the vibration
