Stop in for a cup of coffee

If you push the studs out without cutting the swedged part of the drum, you will enlarge the stud holes in the hub and a new stud is much less likely to be tight when driven in. It can actually ruin the hub. ....and they don't grow on trees.
They usually go out the same way, follow the swedge on the hub that they put in. I will do some pics when I do the cudas.
