Hello I have a vibration at speed and I believe it is coming

This answer was rated:

I have a vibration at speed and I believe it is coming from the rear of the vehicle and it only happens when I am going over 30-40 mph. I have checked the motor mounts and all of the ujoints which were replaced a year ago so I do not suspect them. Can someone tell me hoe do check rear wheel bearings and send some diagrams of the repair before I tear things apart? Thank you
