For the trucks with no shim, which one do you end up getting 2 degrees? or 4 degrees? I have no shim but a new vibration.
I did not notice the vibration at first, its not super sever just a shutter at 30 mph. It is most noticeable under easy acceleration or deceleration. If you accelerated to 30 mph and stay at the speed you are able to notice it. Or decelerate to 30 and stay at that speed.
