Hi, changing front near side wheel bearing and hub, first bearing needing change, not bad considering 150 k miles. All has come off fairly easily considering how rusted all has become in 17 years. The 3 fixing bolts securing the hub itself were in an awful state and rounded immediately. Can I grind the heads off and then beat hub/grounded studs off ? possibly I could change bearing only and leave in situ if not. Any advice much appreciated
