I've pulled my rear third ( regeared) and put my stock third in and it only changes at what rpm and speeds the vibration is felt. I'm wondering if my rear axle is slightly off causing a wierd angle on the drive line that I can't see with my brakes eye. My axle appears centered to me but my pan hard isn't horizontal. Do i need to extend my pan hard more you think?
