Hey C20 Owners

Do you have vibration issues with your stock setup? Mainly those with leaf spring rear suspensions

I have vibrations which I've narrowed down to the driveline. It is speed dependent, not tire/wheel/brake drum related. I've gone thru everything shimming the pinion angle, shimming carrier bearing and trans mount. Up down everything I've tried only seems to move the vibration around but never eliminating it.

I've had the 2 piece d/s rebuilt and balanced twice, new motor/trans mounts. duplicate the issue with rear on jack stands with no brake drums/tires/wheels.

I can't believe GM built this truck to vibrate. it is totally stock suspension.
