first thing- check to see if all your fan blades are still attached. mine got OOOLLLDDD and broke off just from centrifugal force. only other thing i can think is motor problem like valve timing is off or crank is out of balance. MAYBE a hub is locked and you're spinning the front cv's and driveshaft at highway speeds, causing vibes.


-Sorry,I forgot to mention that my hubs were replace with Warn manual hubs so I know when they are locked or not <img src="/forums/images/graemlins/wink.gif" alt="" />

-Yes, I recently replaced upper and lower ball joints on both side and my left tie-rod end + it was realigned after.
My motor mounts seem to be fine(I will have it checked to confirm)

-Thanks,I will check my fan blades tonight I hope that the fan is the problem... valve timing or crank out of balance sounds like...very expensive <img src="/forums/images/graemlins/frown.gif" alt="" />

I have been running with this strange vibration for over 1 year...If I have to spend a lot of money on this vibration I think I will continue and ignore it.. <img src="/forums/images/graemlins/frown.gif" alt="" /> Its my DD and I rarely go on highway. When Im in town I usualy shift when I reach 3000rpm before vibration come)Anyway its not a violent vibration but just enough to be annoying.

thanks
