Radius arm stud
I am changing the radius arm bushings and the stud that the bushing goes on broke when I was loosening the nut. The last thing I want to do is replace the arm. Does. Anyone sell these studs? If not I guess I will make one. I cut the weld and got the old one out. I just need a new one to weld back in.
Thanks

I used to have a site bookmarked for a replacement stud used on the Broncos up through 79 but I can't find it anymore. Try these: http://broncograveyard.com/index.php and http://www.bcbroncos.com/store/. While they don't list that part they may be able to help you locate one.

do you have stock radius arms or aftermarket radius arms? if they are stock i would just get a replacement from the wrecking yard. with the stud breaking like that the rest of the arm may be fatigued and could fail elsewhere on the arm.

Even a new arm is going to have the stud welded on. I'm going to put longer arms on it in the future, or else I probably would just replace it.

your talking maybe $20 for a replacement wreckingyard arm. personally it wouldnt be worth my time to have welded not to mention the safty factor. if the nut was that rusted and it required that kind of force to break it figure the rest of the arm could be compromised.
u have the mad welding skills to do this work also? all things to consider.

The amount of torque required to shear off a stud of that diameter most definitely tweaked the much thinner stamped steel portion of the stock radius arm. Trusting the arm and then welding on it for the second time in its life AFTER tweaking it like that is an idea that few would consider even pursuing much less actually completing. At the very least, welding on it a second time will vitrify the metal even further thereby weakening it more.

I sure in the heck wouldn't attempt fixing it either. I have to replace the same bushings on my truck here this fall, and if they break, I will either get new, or pay a visit to a junkyard. I worked as a production welder for 5 years and I wouldn't trust my own welding skills on the radius arms... Something else, .... maybe..... example, sway bar brackets? Done that one!

My question was just to find out if anyone made these studs. I thank the person responded to it. This little two inch weld is not what holds the axle. The stud presses three inches into the arm and then has two inch weld holding it in. The interference fit is what supports it. Also if I was going to go through the trouble to replace the arm it would be with a new one, not one from a junk yard that may break when I torque it down. When I lift the truck it's getting longer arms anyway. Made by me. However I will run this whole idea by a friend of mine that has fabricated several suspensions for trucks and jeeps from scratch since there is so much concern. The professional fabricate rs that I work with don't see why it would be an issue for someone who knows how to weld. Thanks for the input though.
