Broke a lug stud when changing my rear breaks last week. Tried replacing it tonight. I followed this post...

https://forum.ih8mud.com/showthread.php?p=783693#poststop

Here's where it goes horribly wrong. I'm trying to get the lug studs seated like pskhaat did. But I keep stripping the stud and lug nut. The nut isn't bottoming out and it seems like the threads in the nut aren't durable enough to deal with the torque.

Rather than just replacing the one that broke previously I decided to replace all five. So far I've wrecked 2 studs and 2 nuts. At least I can use the old ones that were still in decent shape, but I'm running out of nuts!

How the hell do you get these things to seat?
 
For got to mention that I do not have an impact wrench. Is that where I've gone wrong? I'm using the tire iron.
 
I've replaced a lot of studs, and made up a little kit I keep together. I use two large flat spacers that's about 3/8" thick and a regular opened end lug nut.
Start the stud into the hole, place the spacer over it and install the nut, pull it in just to start to seat the stud. Then hit it with an impact if you can get your hands on one ( I use a 1/2" IR) with short bursts, checking to see that it is moving in. As soon as the stud starts coming through enough, add the second spacer if you need to. You can always stack regular washers if you need to if you can't find the spacers. The tire iron might be your draw back. The studs really need to be "popped" into place.
Good Luck!
 
I've used an old c-clamp for this twice with success. I slide the new stud in from the back and then use a 14mm deep well socket on the outside of the hub over the protruding stud threads. I then mount the c-clamp on the stud head and the outer socket edge and start turning. It pulls the stud through and up into the socket. This way you are pushing the stud through without using the threads to pull it. Its an older clamp that barely fits up where the shoes are joined.
 
Would it be worth putting antisieze on the stud splines and hub to help ease them in, I expect they may come out easier next time as well?
 
I have C-clamps and gave that method a try. No dice. These things are very stubborn. I'm going to buy an impact wrench today and a couple throw-away lug nuts.

My wife probably thinks I planned this on purpose so I can go out and buy another tool.

I'm a little concerned about the force it seems I need to use for these things to seat. I'm afraid that the impact wrench will just strip the studs. I've got 2 more tries before things go South fast. Joy.
 
Just making sure the obvious is checked.
Correct size of studs? At 10 each for the nuts, I wouldn’t want to waste anymore than I have to!
When doing studs on tractor trailers, we have a spacer to keep the nut from making contact with the thread-less portion of the stud.
Are you trying to align the splines to the originals?

I am interesred in the outcome of this as I carry spare studs and nuts with me incase I break some in the middle of nowhere, I was under the impression I would be able to replace them on the "side of the road" so to speak, with the standard wheel brace or with a socket and knuckle bar. If they won't pull in by hand, I'm going to be in trouble. The studs and nuts you have purchased, are they Toyota brand, or aftermarket?
 
I'm going to get back into this tomorrow morning. I had plans today.

They are the right studs. Toyota parts from C-Dan. I'm getting an impact wrench tomorrow morning. I seriously doubt this is a road side repair. If I can't get 5 in hopefully I'll get 3 so I can limp to the stealership.

I'll freeze them overnight :)
 
Fortunately I haven't had to change any on the road, but my brother has had to in a ute, he broke 4 studs out of six on one wheel and pulled 2 out of the other wheel to get 4 each side to get himself going. He was overloaded and had lots of tools onboard and oxy as well, I can't remember if he had to use oxy or not. I don't expect this to happen to me, but when Murphys Law strikes, and you get a flat tire and break 2 or three getting the wheel off you are in real trouble out in the middle of OZ!
 
I’ll add that you will want to stay away from cheap impacts.;)

OK now.

Impact wrenches rock. How does anyone live without this tool? That’s all it takes. I would say this is an easy road-side fix if you happen to carry around an impact wrench. I also think that the OEM nuts aren’t very strong and strip scary easy. Some steel ones I picked up from “Just Tires” seem to work better. The guy at the counter just gave me a couple. I know they don’t cost much, but it was still cool. I’ve never been there before and now they have a new loyal customer.

You know what is really satisfying? When it’s 11 o’clock at night and you’re covered in brake dust. Things are really starting to look grim and expensive and that special someone says to you, “You should have just taken it to the dealership.” Good times fellas. It doesn’t get any better than that.

Thanks for the help!
 
The power of 'MUD ;)
 
Ok, I confused now. Discount tire didn’t show any aftermarket lug nuts for the 100.
Was he mistaken? When ever I looked at picking up some OEM rims, I needed the OEM lug nuts, 200 bucks a set!
Fyton2v, do you think you can get a part #?
Thanks
DMX
 
Just to clarify, I only used the nuts from the tire place to pull the studs into place. They don't fit the rims.

I bought both the OEM studs and nuts from C-Dan.
Nut part #: 90942-01103 at $7.80 ea
Bolt part #: 90942-02077 at $4.30 ea

I love IH8MUD.
 
Ok, thanks.
 
Yep, impact wrench is the ticket. It provides the `blows' needed to (un-)tighten things. Just like a hammer it's kinetic energy is maintained in each blow allowing for a force multiplier. They are /not/ always the devilish tools people make them out to be :)
