Resposta para "How do I replace a lug stud on 2012 Hyundai Sonata"You have to take the entire hub and knuckle assembly off. I cut off the head of the broken stud and pounded it out, but there is absolutely no way to get it past the knuckle. You have to separate the ball joints, undo the speed sensor, unbolt the upper support from the shock tower and remove the axle. Then take a hammer and a large socket and drive out the hub from the knuckle (goods you tube videos available). Then once the hub is separated, you can put it in a vice and drive out the broken studs, then drive in the new ones from the other side. Try using a torch to heat the hub to free the old studs.
