steering bars are about 2 years old never had the issue before so I don’t think it’s that but still possible. Would one wheel out of balance really be enough to throw it into death wobble? I thought it was all about alignment.
It's not all about alignment, loose components can play a major factor as well as wheel balance (it could have even just tossed a balancing weight). I don't really know anything about your steering setup, but I don't think breaking away from the Y-link often makes sense. What steering system did you move to?
