front drums w/o hubs?

I think there was some smoke over the issue about needing to pull the hubs off: ..........................................
Let's just not lose sight of the actual POINT to my post which was merely to offer a better procedure for separating them if you want to for whatever reason.

There is no smoke over the issue, the fact is that drums should NEVER need to be separated in order to turn them, and I never have done so. In fact it is more accurate to turn them as a hub / drum assembly because that's how they go down the road.

Your method of separation is not very good if you expect to save the drum. Swedging "varies." You might very well get one or two drums separated the way you describe, and the next two.........you might end up with a mess.

The studs ARE swedged into the drums, and the only reliable way of separating them is to cut, grind, otherwise remove the swedge.

There is absolutely no reason to do so unless you are replacing the drums, and in that case, you may not care.........about the condition of the drums
