Default Highway Vibration

I have a bad vibration starting at about 40 mph I haven't been able to figure out. I have played with my driveshaft angle and at first it changed and maybe helped but now it is just a high frequency vibration. It feels like driving on the rumble strips on the edge of a highway going 70 mph. I am changing all the u joints soon. Is there anything else I should check out or mess with?

The PF's have rear upper/lower bars (control arms) that the bushings go bad which cause the wobble issue

Download a program for your phone called VibSensor. It allows you to measure road speed vibrations in hertz and will give you an idea of what to look at based on those numbers.

I have a new carrier bearing, I have replaced all the lower control arm bushings. I really meant tires. They are 15x7 wheels.
