so after caliper problem issue is fixed another issue has cropped up. looks like i tightened up the wheel nut too much and the bolt stud snapped this is front drivers side wheel.

can get a new stud easily but how do i go about replacing it? does the hub have to be removed or is it just a case of using a punch and hammer to knock out the remaining stud and replace it with a new one?

You have a shouldered flange (back side) and ribbed metal body of the stud in the axle hub and all the threading (pictured) sheared off. You might be able to heat the hub a bit and hit it out, yes.

Would there be clearance enough to insert the replacement?

This is part of the reason I use anti-seize on lugs.
1) Yes, you have to reduce torque with "lubed" threads. Torque specs are for dry thread.
2) No, your wheels won't fly off whilst driving. I'm living proof of that as well as all my friends.
3) I've heard the large size of lug hardware provides a broader range of usable torques.
4) Rusty, scaly threads drag and grab to the point of hanging up-they chatter-and that's what happened in your situation.

Which car in your signature was it?

Depends on the degree of difficulty. I would remove the wheel though. However always use a torque wrench in tightening wheel nuts. This prevents what you did, and helps prevent run-out with the roters.

On my Accent I had a front and rear stud snap. This was from messing up the threads using an air wrench to tighten them down.

The front was a PIT due to the heat shield behind the rotor. Hyundai has it as an integral part of the hub and the only way to remove it is to press the hub out of the knuckle.

But there is one spot where the shield does not cover the rear 100%. So I positioned the broke stud there and knocked it out. But to reinstall I had to bend the shield 90* to gain enough clearance.

Terrible design but a bent up shield is no big deal.

Make sure the studs you get are equal to the ones taken out in length.

Depends on the vehicle, some are easier than others, some fronts or backs differ as well.

BTW does everyone here expect everyone else to guess which vehicle is involved in a technical question? I'm not going to dig back into the OP's posting history just to figure out which vehicle.

The last time I replaced a stud it was on my wife's 2002 Corolla. I did it the 'wrong' way by giving it one solid smack with a heavy hammer (eye protection mandatory!) and it popped out of the hub. Installing it was just stacking a bunch of greased washers (like a poor-man's thrust bearing) under a reversed (flat side facing in) lug nut and wrenching it down until the stud flange bottomed out. Do NOT go any further than that or you will stress the new stud and probably ruin the threads and even possibly break it. Don't be an ape.

I take no responsibility for hurting your car or yourself if you do it this way.

Unless it's an optical illusion, you can see the stud thin out where the rusty thread is. This stud was overtorqued several times before it finally sheared off. It can be replaced, but I would check other studs for this and replace as well.

i think where its thinned out its stretched or something.
car was the celica.
looks like it should be a straight forwards job if i follow this guide.: https://www.celicahobby.com/forums/ubbth...to-replace.html

iv got the replacement stud so will fit it tomorrow.
will look to order a whole set of replacements for the car.

Yes and it's a sign that the stud is now junk, as the internal structure of the metal changed and its tensile strength is severely compromised.
Inspect the rest of the studs for this thinning or thread deformation and replace ASAP. Your life could depend on it.
I'm not the one to cry safety, but seeing this stud doesn't inspire any confidence in me that the rest are fine.

I think this is an excellent use of a tool to remove and put in / remove wheel studs because you can leave the hub in place.
I can not post just a picture of the tool removing a wheel stud but you can see the images in the Amazon link. I have this separator tool and believe it is strong enough to do the job but might open large enough for your car. Putting them in with this you would flip it so the tightening screw will face away from the hub to give plenty of room.

Exactly. Have had a couple MDX recently with broken studs as the customer forgot to remove the hub ring when they put their summer OE wheels back on. On the front of an MDX you can not remove/install the stud without removing the hub. That means pulling the hub, when you remove the hub, you have to replace the wheel bearing, that means removing the front knuckle, and after all that, a four wheel align. Turned in to a $700 job. Same job on the back, one hit with a hammer, stud out, push in new stud. Done.

I would never ever use anti seize on the threads, but using closed end wheel nuts will keep the studs clean. The only time I see corroded wheel studs is when people have ditched their OE closed ended ones and replaced with open ended ones that exposes the stud to the elements.

I would not. You are looking for a friction fit. Try to somewhat line the splines up.

I'd put a thin coat of anti-seize on them.
