I have a strange trouble that my mechanic dont find. I have a vibration coming from the rear at higway speed it start at 100kmh and goes crazy at 140kmh.
I switch the tire ans remove the driveshaft and no change.
It's a 2008 V6 4wd
Someone can help me ?

I don't know if it would make any difference with the driveshaft removed but I'd disconnect the 4WD ECM. It's mounted just in front of the glove box.

possibly a damaged rear drive axle...also check rear areas for any damaged suspension parts...

You think the computer could make a vibration ?

By "switching tires", did you mean you put both rears on the front, or just switch them from side to side? You could have a bent rim, which would still balance ok off the car, but will certainly cause a vibration back on the road.

Don't know but it's easy to drop the glove box, unplug it and find out.

[Dr. Dyno]

Are you saying the vibration started when you put your snows on and no one suspected them? :doh: :roll:
