Hello, Let me ask a few questions first to see if we can get to the bottom of your concern.

does the vibration occur when braking?

does the vibration start at 50 mph and continue?

does the vibration go away if you let off the gas?

When braking, I haven'i noticed.
Yes vibration is most noticeable when I reach 50mph and above
No vibration remains when let off the gas

ok thanks for the information. I t sounds like you have a tire or wheel balance issue with one or both of the rear tires.

try to rebalance the tires and have them checked for belt separation.

rotate them to the front and see if the vibration is now coming from the front.
