    I have 3 questions.

    1. Is this a dot infraction? The other bolts are tight and it's not leaking.
    2. Am I destined to break more if I leave it for a while till the weather improves?
    3. The stud snapped flush with the hub. So there is probably 2" of thread in the hub still,. Would you remove the hub and try a drill press and ez out, or would you try to do it on the axle ?

    Thanks
    I'm still learning at this, but I'm doing my best

    If you run legal loads on good roads id stick a hubcap on it to hide it from prying eyes and wait for a warm dry day to deal with it. Run over weight on rough gravel roads ir go into muddy job sites and ya might want to fix it asap.

    Stick a nut over the broken stud and weld it from the inside out. While it's still hot after welding put a wrench on it to remove it

    How? Just curious. Its not like the wheel's going to fall off or anything. They pull those shafts right out when they tow the truck or when a guy has a diff blow up and they need to get it home.

    OP, if the stud broke from impact with a log or something I'd just change the one and be done. If it broke from fatigue or corrosion I'd consider replacing all of them.

    Manufacturers install 8 or 10 studs fo
    Because it has as many needed. And if one breaks and gets ignored you may end up with all broken stud. I call that preventive maintenance.

    If I planned to run a little I would make sure the the others will tighten to spec.
    This is one I did. The distance from the end of the bolt to the broken stud is how deep it was broken off in the hub. Tried a drill and easy out first. KIMG0319.jpeg Spotted with a stainless rod over and over. Then welded to the bolt.
