If so it you and balanced tires, you likely either have a bad Ujoint, bad Ujoint angles (theses can create a lot of vibrations) or a drive shaft that is not balanced. ----------------- TheSnoMan.com |

You could try rotating the tires to see if the vibration changes place. While doing that I recommend a hand spin of each tire to see if it is obviously out of round or has a bulge. How fast are the tires spinning when the vibe happens? 5th and 2400 is kinda meaningless without knowing the gears and tranny ratios. On mine, 2400 in 5th would be about 85 mph.

And you try to pass yourself off as a expert too, Shame!!!! Not surprize coming for someone that tells people to spin the tires is reverse while in 4x4 to remove drivetrain stress. You are all show and no know. ----------------- TheSnoMan.com |
