if you cant fix it with duck tape you must not be using enough!!

If you have external brake drums & have cut off level with the hub....if not cut level with the drum....then drill the centre of the stud out with a centred 3/8" drill about 1/4" to 3/8" deep....support behind the stud so everything is firm.
One good whack from a big hammer [not a carpenters or 2# ball peen] on a 5/16" straight punch will do the job or alternatively, same support & use your press on a short 5/16 grade 8 bolt straight & firmly, but be careful those studs will pop like a bullet.

I have always used a 2# Machinists hammer (Baby Sledge) and support the flange of the hub from beneath with a hollow steel tube ot a large socket. One healthy whack on the stud will do it. Rge factory instructions for the CJ-Jeeps The TM9-803 for the MB/GPW also instructs the same. When installing the studs,you can get by without swaging or staking them in place. If you prefer to do so, you can upset the metal around the stud with a prick punch.The key to a successful stud installation is the use of proper part nnumber studs. The demountable drums attached with 3 screws on CJ-3A, CJ-5, M-38/M-38A1 use different studs than do the MB, CJ-2A, and CJ-3A hub.

The proper way to do this is to use a swage removing tool that is very expensive.
The other way to relieve the swage is cut to off & drill so that the swage collapses into the drilled hole when using your punch & hammer.
Just bashing with a hammer, as someone always comes up with, but obviously has not done much, rarely works on MB GPW OEM hubs as I have experienced, no matter what the books say.

Post pictures of what you have done as far as drilling & what you are using to support the hub/drum & the hammer you are using. Then we can go from there.

Boy I remember with mine early on I tried all those ways and ended up taking them to a shop and they pressed them out, checked my drums and put new ones in for me. He was a friend so it wasn't too bad but it is a bear of a job.

i started trying to remove them with just a hammer (friends suggestion) and when that didnt work i got on here and started searching and found some suggestions so i cut off the studs and started drilling i went a little ways and tryed hitting it, nothing so i went a litle further nothing until when i tryed hitting it again the punch put a hole in the bottom so i tryed again and same thing now im stuck as to what to do i even tryed doing a different hub and got the same result

OK now we can see....you need to grind off so as to be perfectly level with the hub & I would be using a bigger drill so as to be closer to the max you can drill without going into thr hub. For the rest centre punch the centre of the cut off stud, so you don't have thick spots, then drill & punch with a good hammer.
No need to drill from the inside

Steve's experience is not abnormal & just pressing these studs out without swage removal usually stuffs up the hub.
I remember in the OZ military, with WW2 jeeps when rivet damaged or worn, we did not just change brake drums but complete hub assemblies.

Now help others with a picture or 2 of what happened to the swage which collapsed internally on the stud/s you knocked out. As well others may [& one should, but won't] learn that reading a book doesn't always cut the mustard. Especially with this stud removal business, as well as many other things.

AS WELL one can drill from the other side or inside @ a larger diameter than the hub stud hole [helps if you have a good slow running drill press fitted with a stop].
Then you don't need to angle grind the stud off.
Be careful not to drill into the hub & after the first one is drilled deep enough, set your stop limiting drill travel.
The stud will knock out very easily.

I stand behind using a hammer, it works does no damage and saves a lot of time.

I truly wonder whether that broken record has ever replaced a WW2 Jeep brake drum? Then again he is unique!

Common sense tells one that something very hard in composition, swaged to a larger size than the original hole, a hole in relatively soft cast steel, will remove the soft material if pressed out. It would also do so, if it could be hammered out.

The guy in the following presentation is using a 20T press, primarily because a hammer just doesn't work, normally.
He admits 1/2 way thru the pictorial how he has stuffed up the hub & has to weld some studs to the drum to stop them turning in the enlarged hub stud hole. Pic's 10,11,15

And that is what happened to a couple of my studs. They had to be tacked back in. It wouldn't have been necessary but others had wrenched off the LH studs over time, so if you are going to do 1 side just do all of them. all RH now.

distroying the hub is exactly why i asked and didnt just keep beating. it did still take alot of force to remove the old ones and i would not have been able to remove them without grinding them off first. i will post pictures of it tomorrow

here are the pictures you cant really see how the swage collapsed into the hole but you can see the burr at the top used to be part of the swage and the drill bit in the picture is the same one that i used to drill the holes and it wont fit into the hole now
