Broken stud

[Arefbee]

Morning all. Hope all are happy campers, happy Fathers Day if applicable
So, I took the PrimeTime for fresh tires. The OEMs looked pretty old and cracked.
All went well, except they managed to break one stud off half way up.
I still have 19 more and could put a lug on the remnant and be fine for years... but I'd rather do it right.
Question for anyone who has ever had this happen. Should I replace just the stud or the wheel hub? $5 plus (my)labor for stud or $40 for the hub.
This is an 8yo trailer, had the hubs off 3 years ago, never had to remove a stud before. My tech level is knowledgeable amateur. I don't have specialized tools but know a good machine shop and I have 10 different sized hammers How hard will it (probably) be to remove the stud from the hub?
(I did a search for old threads but could not find any; could be b/c iPad browser is less than stellar)

Just replace the stud, it’s an easy job just time consuming. You don’t need any special tools, just get a bunch of flat washers with a larger hole diameter than the stud and use them to pull the stud all the way in.

It's been a few years since I've had to replace a stud, but I did do it with basic tools...BFH...and a little sweat. At $40 for hub, I'd call it a toss up. Spend the time removing the broken one or just get a hub and be done.

If your lucky you may be able to drive the broken stud out with out removing the hub. Good luck which ever way you get it done.

Curious, how did they break the stud, over torquing maybe?

I agree it’s a toss up I have replaced several studs one or two practically fell out others tested my sanity. Honestly I might lean towards a new hub just because my luck isn’t always good and in back of my mind I am thinking about changing tires on roadside and another stud breaks odds would be extremely slim but it would be there

I’d love to know how they managed to do it. I had the lugs off to check the brakes last, hand started each one so no cross threading. checked the torque a couple of times after, never had a battle.
Since there is so much stud left I’d say it didn’t bind until halfway up the shaft. The rest came off easily. I think someone was rushing and tried to plow through too much rust. They could have tapped it instead of breaking it but weren’t equipped to.
Well I’m going to try the stud before I order the hub.
Thanks for the feedback.

A machine shop will charge you $10 to remove/replace a stud if the old one is rusted in there.

I’ve heard that half the diameter of a bolt is enough length to hold a nut, but I would change it.

Just asking but if a shop broke your stud off.. Shouldn't they be finding someone to repair? Not saying I'd let them fix it.. But they should be getting a repair person to make it right. Either way it's not hard to swap one. Used to do it on the trails all the time on my jeep and lifted ranger.

On our previous fifth wheel my wheel sheered off going down the highway and I lost most all of the studs on that hub - and the ones that weren't sheered were messed up beyond use.


I replaced all of the studs in a shopping center parking lot and continued the remaining 7 miles to my house.

Last weekend I replaced 5 studs on my grandson's Jeep Wrangler - they snapped off trying to remove the wheel to replace brake pads.

As has been mentioned - it's not a real difficult job, just takes time and it is DIRTY!!

Main reasons I see studs breaking are either not using a torque wrench or greasing the studs first and still torquing to the dry torque values.
