Vibrations...

Seems not everone reads what I wrote earlier..?
Done this: anged the pinion good, replaced driveshaft, u-joints, new tires & balanced them, rubber mount & pro'ly something more I can't remember just now...
So I reckon it must be the gearbox, or..?
We all hear you loud and clear
Just alot of people spit balling answers, happens all the time on here.
Just because the tires and wheels are new does not always mean they are good.
Start over and do the simply things first.
Has it done this since you have had the car? Or did it start after changes were made?
