Re: annoying vibrations between 70-80 mph, need help??
Have the rear u-joint checked. Mine went bad and that is how it felt. To be more specific, I noticed it more when on the throttle and less when coasting, and seemed worse at freeway speeds. Had it replaced with a greasable one, and the noise/vibration is completely gone. Good luck
