Had a car (GM) once that had a horrible death wobble that all of a sudden developed. Took to for front end work and it still did the same thing. After about 3 trips to the shop, one old timer mechanic figured it out. He threw away all the new fangled electronics and just studied the thing out with common logic.

It turned out to be the tread of the front tires. Each groove of the tires was wearing different causing dips and highs in each line, and they were highs and lows beside each other. When the tires rotated and got into synch with each each just right, those highs and lows on the tread caused the front end to shake violently and the steering wheel to pulsate almost out of control. I got new tires and it never happened again.

Before doing anything that will add up to a huge bill, have someone look at the tires. Make sure the tread is even on them, and make sure they are true round. That was another problem I had with another set of tires once, that caused a wobble. When they were in just the right sync, everything shook violently.

Start with the tires, have them checked and make sure tread is even and they are true round.
