Took the hub/drum assembly off the A100 and can't get the drum free from the hub. I want to change the LH thread studs to RH threads. I used PB blaster and a 20 ton press and no luck. What else can I try?

Did you cut the swages off the studs ? (Assuming they are still there)

The pic below shows the studs before and after swaging, if you don't remove the swaging before removing the studs the hub can be damaged.

I had the same problem on a 67 Barracuda.Tried a press with no luck,ended up giving it a good wack on the end of the hub with a post maul and finally cracked it loose.

Here's the cutter used to remove the swages, an automotive machine shop might have one and Goodson sells them.

Yeah you need to cut the swedges.Id almost say if you got carried away with the press the hub might be bent.If its bent good luck.It will need replaced.Had a brake mechanic try what you did once.New drums fixed what he did along with the hubs.Rocky

Had no idea about the swaged studs, but a bigger hammer took care of it! Now I have to get new studs, and I want to change the LH for RH. Is there a particular part # I should ask for. Do the studs HAVE to be swaged when I install new ones?

before you use that hub again, put it back on the truck and check the runout of the hub to drum face. if it's bent, you will be not happy after you install your new drum and studs , then find out it's bent...........

In theory, there is no difference between theory and practice. In practice, there is.

Thanks everyone for the info. I did get the drums and hubs separated. I don't think the drums are damaged, but I will check. Mopar obviously did some strange things a while back. Still can't figure out why they had LH & RH threaded studs. I'm for sure going to change that!

with that being said, i have had to replace many hubs over the years that had been bent by not removing the swedge on the studs. mopar was famous for using them. gm & ford, not so much. this was mainly because there was no support under the stud being removed. however, IF you got the stud out with the BFH and didn't somehow bend the hub, then you said bad words when the new studs fit really loose upon installation. why ? because upon removal, the swedgs ground the serration hole oversize on the way out. then it was either tack weld the stud to the hub, or try to find another stud that was slightly[approximately .010] larger on the spline od. than the original application. sometimes it just isn't as simple as it seems.

I have never come across a swaged brake drum before. Yes the holes are slightly larger now, but is that going to be that much of a problem? I mean when your running down the road, with all lugs tightened, what could go wrong? I'm not trying to be a butt about this,but I've owned and worked on a lot of my own cars over the years, and never encountered such a thing. Why would you seriously need the studs swaged? Just wondering if it's absolutely necessary. I just thought of something, why aren't the rear drums swaged on?

Nothing wrong with leaving the drum loose on hub, AS LONG as the drum does not get caught on edge of stud knurl when wheel gets snugged down.

The problem will rear it's head at 2 am on a dark and lonely night when your trying to remove a flat and the studs are spinning.

I have said this before here,you don't want to weld on those hardened studs (and all studs are grade 8 hardened to my knowledge). It will embrittle the head and it will fall off. In 6 months, or 6 years, it will fall off. In my case, 10 studs tack welded to hub, 7 heads came off 6 months later. Moroso studs.

Not to hijack here but I am getting ready to tear my A-100 straight axle apart for the my 65 AWB car. Are the swedged studs something that was typically used and is this cutter something I need to purchase prior to disassembly? thx...
I want to stay drum brakes but was reading where the 10 x 2 1/2 drums used for a 65 Coronet spindle are also interchangeable with the A-100, and I don't recall having the swedged studs on the Coronet front drums.


...FAFO...

65 drums should be swedged also. You can get the studs out without that cutter by drilling the heads out from the back. But even with good drills and a drill press this will take some time.
