I had death wobble on my Jeep. Same POS suspension design. Changed tie rods, ball joints, hubs, tires/wheels, control arms, track bars, steering stabalizer, pitman arm.. After thousands of dollars, it finally turned out to be the driver side axle shaft u-joint that cost me 35 bucks.. Go figure.. Most common is the track bar. But it can be damn near anything up front. I've seen guys have issues with just one part or a couple working together. Just start looking for worn out parts as a place to start.
