Thanks jwed and Brian.
I've experienced driveline vibes before and am familiar with the higher frequency thereof. This is clearly at wheel speed frequency. (as mentioned earlier)

It's all original ... torque tube with original wheels.
I have another pair of mounted bias-ply's that I'll try on the front.
Thanks to Ogre also. I'll move them around and see if it calms down.
I'm ordering a kingpin kit too.

Thanks guys.
