Wobble/Virbration at highway speed when downforce on front

[00N8]

I've searched high and low and all the vibration / wobble threads I could find were related to tire balance and seemed to be consistent at a specific speed.

My situation is when at high way speed, if I drive over a dip or bump and the front of the rig pushes down some, the wobble can be felt and heard, once the shocks even out the movement of the vehicle the wobble stops.

Any thoughts?

I would have suspected the tire too.

Maybe check the front bearings and CV's in the axles.

Check all rear control ARM bolts. One time I swore wobble came from front, practically pulled whole hub apart on side of road and saw no issues. Went to back and was missing a control arm bolt...not a good feeling to see that missing...good luck tracking issue down
