Aloha everyone,
Was installing my 2nd CV half shaft today and when putting the hub flange back on I broke 2 of the studs (see picture below). I have read through the forums and can't find a how to. I have tonight and tomorrow to fix this and need help asap. Can anyone help me get started? I also am going to pick up a torque wrench tonight. The FSM says 31 N-m torque on the hub flange nuts. I will be very careful this time.
The absolute best way requires a welder. Pull the other 4 nuts back off and pull the flange to expose what's left of the broken studs. Thread a disposable nut about halfway onto the stud and weld the center of it. Then you can use a wrench or an impact to remove the stud.
It doesn't look like there will be enough threads left to install 2 nuts on a stud and jam them together... but it's worth looking at. Thread one all the way to the bottom, then thread another one down on top of it. Put a wrench on each nut and tighten them against eachother. Then you can put a wrench on the bottom nut and try to loosen it, and because the top nut is jammed it will apply the torque to the stud, hopefully loosening it.
If either of those are not an option, you can try a small pipe wrench to loosen the studs, but try this last because it will damage the threads and prevent you from being able to try the other options. Good luck.

I thought these studs were pressed in and not threaded in? If they are threaded I can probably try the 2 nut method. I can't seem to find the replacement studs at autozone or oreillys (we have napa here but i think they are closed tomorrow/tonight).
The wheel studs are pressed, the hub studs are threaded. If you can't find any locally in time, you can use a bolt in its place to get you by.
Can you help me find the part on autozone or oreillys? I don't even know what I am looking for or the specs for the studs. Sorry I'm a little panicked right now. What are the specs for the double ended stud? I can't find it in the FSM. The other hub studs were rock solid. These just snapped right off. And by "get me by" you mean I can use a bolt short term as long as I am not in 4WD?

Those studs seem to be ghosts, I'm not seeing a definite application on anything I find. If I were you, extract the broken ones and take one to whatever store is open tomorrow and try to find a bolt that matches the depth and thread pitch. As far as getting by, you'll be fine with 4 studs in 2WD, if you can get a couple bolts to replace your broken studs you'll be fine in 4WD as well.

As we say here in hawaii u da man. Mahaloz for your help. I will try the two nut method and pull one stud and see what I can find. I will post an update when I get it out.

Very happy to help! Best of luck, look forward to the update.
Oh, and in my experience NAPA seems to have better resources for finding parts that Autozone or O'reilly"s. I bet if you took your broken stud to them they could match it up or find one by application. I'm pretty exclusive to my local NAPA, the other 2 stores are usually just a waste of my time, unless all I need is washer fluid.

Is this the part I am after? It says the nut is 8mm but mine are 12mm?
I ended up replacing 3 of the hub studs with M8 25mm long bolts using the flat and cone washers (see picture below). I picked up a torque wrench to make sure I wasn't over-torquing the nuts. Sure enough I got back from AZ and when I tried to replace the hub flange and torque down the nuts to FSM spec'd 23 ft.-lbs. another one snapped! The previous owner must have bought aftermarket sh** chinese hub studs because they all sheared in the same spot well under the 23 ft.-lbs. of torque (see image below). When I did the other side the stock hub studs were insanely tough and took well over 23 ft.-lbs. of torque. I will be careful which ones I order now to replace and wonder how long I can run the zinc coated bolts. I don't need 4WD too heavy for now so maybe I will wait. I am going to speak to Toyota Parts Department and see if I can get OEM parts...I bet they cost an arm + a leg. Anyway, now I have both front cv shafts done, new sway bar links, and my girl is running cherry for now.
Tomorrow I'll be on the rear brake shoes....joyyyyyy. Mahalo moto809 for your help.
Nice job! Yeah you got some cheap studs in there for sure. In all reality the bolts are just as strong as the studs, you'd be fine if you needed 4WD. The only reason studs are used is they provide a more accurate torque value than a bolt. Replace them when you can, but in the mean time I wouldn't worry about having bolts in their place.
Have fun with those brake shoes!
Nice work! These are the worst kinds of repairs when stuff starts breaking. You think you have a big box of bolts until you realize you dont have what you need
Torque values are affected by dirt n grime, clean threads torque more uniformly. A little dab of blue loctite goes a long way too.

I use anti-seize grease. I've used both the blue and red loctite in manufacturing and not a big fan. On my archery equipment I use teflon tape on everything, same with my rifle scopes. Starting brake shoes now. Let the games begin! Mahalo everyone for replying to this thread and being so helpful. You guys deliver every time, stoked.

This is where under paid (and in general) counter people at a pull your own parts salvage yard are hero's. "I need this $19 part, oh and I've got two pockets full of misc bolts and plastic fasteners", " that will be $19."
On that note my coffee can of misc parts needs a top up.

Yes indeed sir, unfortunately we have no salvage yard here. One of the things I miss about the mainland is salvage yards.
