Help!! Broken wheel studs

I was trying to change the brakes on my wifes 2000 Dodge Grand Caravan this afternoon, and I broke a wheel stud, and stripped another. I got to NAPA just in time to get some new wheel studs, however, I looked up underneath the van, and it looks like there isn't enough clearance to remove them without removing the hub. I did see in another thread where someone wrote that you can rotate the hub, and remove the studs one at a time. I saw in another thread where someone said that you had to remove the hub in order to replace the broken studs. Which is correct? Also, if I have to remove the hub, do I have to buy any seals, grease, etc., or can I just remove it, and replace it? BTW, I just happen to have some large sockets, never used em.

Nevermind, I got it. No hub removal. If the bolt was 1/2mm thicker, it wouldn't have worked. Just for future reference, I was working on the drivers side, and the only place to get the stud in was on the side facing the front of the car.
