Front lugs two are broken how to remove them?

When you do disassemble replace all the lugs and lug nuts, remove components as needed to expose the hub at the wheel bearing area, at that point you should be able to drive them out of the hole and then can pull new ones in by reversing the lug nuts-have extras- and stacking a couple of washers large enough to clear the shoulder of the stud and use air gun to pull the new studs in the holes. If lug nuts are capped you will need to buy regular uncapped lug to do it. Or the hub has to come out and press the new stud in from behind.
