Tread on tires is about 25-30%, Im thinking that may be a cause for it starting to happen.
If you have to drive at that speed, try swerving slightly to shift the weight of the vehicle to one side or the other. Do this just before or during the moment of the onset of the wobble. I used to do this and it would allow me to pass through the death wobble zone and continue up to speed.
Obviously this is not a fix, and you should really fix the mechanism that is causing the wobble, but it's a workaround if you must drive it.
Check your track bar, make sure it's not loose. Get new tires if they are badly or unevenly worn.
