Hello,

So I am sorry if this question sounds stupid, but this vehicle is still new to me and I am trying to get used to all the little quarks. I was driving on the highway today doing about 55 when I hit a bump. The rear of my 46 Stylemaster Sedan began to vibrate heavily, at one point I thought I had broken the rear end. I began to slow down to about 40 and it went away. After driving a couple of miles at 40 I sped back up. No vibration. I drove a couple more miles than hit another bump, and the vibration began all over again. I immediately slowed back down and it went away. If I continue driving at 55 the vibration continues till I slow down. What the heck could be causing this? This is the first time I am noticing this issue
