If its just a stock trackbar, you can buy a full replacement unit from Crown Automotive for about $50 and not deal with the headache. It'll have a fresh ball joint on the steering end as well.
Mine is rusted in. I wish I would have seen the price of the whole track bar. I need to do the control arms next. I am thinking avoit just buying thr while arm with the bushing. I think the price is less 5 bucks difference.
