well sat. we scaled the truck out messed with the preload and messed with the pinion and we also moved the rear bars a little ... havent got up to top speed yet to see if the vibration was still there but it leaves straight and hooks alot better
if this isnt the problem then im going to take out the drive shaft and make sure its ballenced correct
oh yea it hit the scales at 4559 lbs (this is before we messed with the four link and set the preload)......my truck needs a diet hahaha
