Need help diagnosing vibration
Vibration started about 5 months ago. Last repair I had done before that was new rear brake calipers.
Vibration only occurs at speeds over 55mph, most pronounced between 65-70. The dash rattles, floorboard vibrates, etc. It's felt all over.
Things I have done with no resolve:
new tires
removed front drive shaft and drove
replaced both U joints on rear drive shaft.(the said it was balanced but I don't know that they had the equipment to do it?)
If you left off the gas and coast at 750rpm's, the vibration remains so I don't think it's related to the engine. The vibration feels the same speed as the drive train. If you hold on to the 4x4 shifter, you can feel the vibration there.
I just don't know what else would be vibrating? I suppose I could remove the rear shaft and drive it to see what happens.
Any advice?
thanks,
