Do NOT just pound the studs out. This is if the studs are still the original.
The studs are swaged from the factory, to hold the brake drums on. If you pound the studs through, WITHOUT grinding the swaged area down, you run the risk of enlarging the knurled area of the axle or hub, depending on whether you're working on the front or rear brakes. Once these holes are enlarged, new studs will spin in the holes. Hope this makes sence.
I'll see if I can find a pic of what I mean.
Here, the stud on the right is NOT swaged yet, but on the left it is. Pound that through, and it could mean trouble. A dremel or even a good flat file works fine.
I wouldn't be posting this, but I've ruined a front drum in the past by trying to pound it through without grinding the swage down.
