I found two broken lugs on the right rear. ???  And, I'm trying to replace them.  I thought I could take the nut off and hit it with a hammer and punch and it would come out.  I know it was a little more complicated than that A BIG HAMMER AND HIT IT HARD!! :-\  Well it has not worked out that way.  BIG hammer sounds like it is hitting solid, lug no move. :'( 

So now here I am HELP!  ??? How do you get the things out??  If I separate the drum from the hub and hit it directly with the BIG hammer, will it come out.  Next question is how do you separate the hub and drum?  Can I use a draglink socket and take the screws out??   A BIG screwdriver won't work. 

Somebody share your experience please??

To replace the wheel studs, you have to take the hub off the axle so you can take it to a machine shop that specializes in replacing wheel studs.  They have to be pressed off with a hydraulic press (thousands of pounds of pressure).  Please don't try anymore with a hammer-you could cause cracks in the hub that you can't see.  Good Luck, TomC

Hydraulic press is best. I removed the screws that hold the drum in place using a small dull chisel to start the screws turning.  Drum should not be holding it.  Make sure hub is supported close to the stud before hitting it to prevent the hub from flexing.  Hope to see ya'll next week up here.

What does the manual say?
Mine press in from the front (big press) & are retained by a nut on the back.

You have removed the hub from the axle, haven't you? If not, those hammer blows won't do the wheel bearings any good.  :o

Having fun yet?

John,
I don't think sand is the form of silicone used in lubricants . . . .  :o  ;D

John,

I just did this in May.

You lucked out if your hubs are Al like mine. If so, you could have easily pulled half the hole out with the stud.

I would never have the guts to hit those studs as hard as it would have taken to remove mine. I used a BIG sledge and all I got was a very bouncy hub!!

I also found that 4104s have two different length studs. My '54 uses the longer ones.

I had to change all mine on one side because the threads were stripped on three, just decided to change all while the hub was off.

I had to use a 40 ton press that just barely got some of them out.

Next time, since the hubs are Al, I'll heat the hub around the stud hole to make things a lot easier. I also used anti-seize on all studs.
