You really need a press to push them out. I forget, but don't the front drums come off the hub, and you'd press the lug studs out of the hub?

The ONLY safety device we need is a 6" sharpened steel spike bolted to the center of the steering wheel of EVERY vehicle.

The front lug studs are swaged in place at the factory. After assembling, a small amount of the stud shank metal is displaced, forming a small ring or bulge to hold the drum in place. It's not necessary, since the lug nuts hold everything together, but they did it for ease of handling the sub-assembled parts. Removing the swaged material can be a pain. It sounds like yours are still swaged, which indicates that your drums have never been replaced in 54 years.

You have several options:

    - There's a cutter available to run down over the stud and cut the bulge off. It resembles a deep hole saw, with an inside diameter the same size as the stud shank. There is some risk of damaging the drum and/or stud if you're not careful. Do a search of the forum to find a link to the tool. I think it costs around $40.

    - If you're replacing the drums, just use a grinder or cut-off wheel and get rid of the swage, which extends a bit lower than the surface of the drum. You'll probably hack up the drums, but new ones are cheap. New studs are also cheap. This is what I did.

    - If you try to just muscle them out with a press, be careful. You'll likely ruin the studs, and maybe the drum and hub. When you push the enlarged stud through a smaller hole, something's got to give.

    - Some people have pounded them out with a big hammer, but I don't advise that - damage is really likely.

Good luck.

Thanks so much. I used a file to get that area around the stud that the factory. Then they came out using a big{OLD} socket on the backside and pressed them out in my vice. Almost easy. Thanks again.
