Changing lug studs

[ken79fj40]

I've gotta be doing something wrong here. I just started putting my 40 back together last weekend. I've had a broken rear lug stud since I bought the rig 3 years ago, so I figured I would change it out. If memory serves, these things are just pressed in right? I've got the axleshaft out, and was pounding the crap out of it. Wouldn't budge. I tried the same thing on my donor 60 axle and same result. Do I pound harder or should I bring it to someone with a press? I would really like a rolling chassis by next weekend, and this is buggin the crap out of me. Seems like it should be simple.

Hit it harder..
Or use heat..
they are pressed in

BTW, just buy a new stud.. taking one out of a donor is a bit silly..

Cool, will do. I was intending on buying a new stud. All the parts stores are closed in the sticks on sundays.

Studs are cheap. I'd replace all of 'em, just for the piece of mind. I've caught wind of too many people doing restos who leave in old lugs and have 'em get sheared under higher than normal loads (muscle cars or old trucks with higher torque engines), and almost getting into accidents because of it.

you are supporting the flange and not just banging on the stud , right ?

You could lay a Mig bead on the button of the back of the stud(careful not to weld it to the flange ). that ought to get it hot enough to knock it out.
