2002 passport vibration problem

I just bought a 2002 passport and I have this annoying vibration after 60 MPH, I had the car balanced and aligned and help some but the problem still there. any idea what could it be??

How's the tires? I know my 2002 rodeo vibrates badly over 60-65mph due to my horrible worn factory tires. I'm tryin' to get 40Kmi out of them :crying: . The factory alumimum wheels can be a bear to balance if you have those. Word is you need to have them balanced on a 'hunter 5000' road-force balancer to get the job done right.

wow, 'hunter 5000' road-force balancer-- now that is very specific!!

isuzu must own stock in that company or something..hehe

i had a vibration at high speed, it turned out to be the roof rack....the side knobs that titghten the cross bars wasn't tight.

tires were out round, but that's only part of the problem, we change them but still a problem

thanks

lost a wieght on the drive shaft?

I just read a similar post elsewhere that said the problem is that the back wheels are not centered. There apparently is a centering ring that is placed on the hub after the wheels are on that will keep the wheels centered.
