Brake Drum Hub Assembly Mystery
Do not just press out the studs to remove the drum, if you do your hubs will be trash. You must cut the swedge from around the studs. There used to be a tool to do this, but it is no longer available. The best method I have seen is to use a 5/8 hole saw with no pilot drill to cut away the swedge from around the studs and remove the drum. You may also need to grind away what's left of the swedge after the drum is removed. Failure to do this and just pressing out the studs will result in the holes in the hub being too large for the studs.
