All I can say is just snug it up good if you're using the lug wrench that comes with the vehicle. Or you can always buy a torque wrench and keep in with you just in case.

Philsey, I think you missed the whole point of my post!
The point is that there is not a 5th Gen weak wussy wheel stud problem because a few people have had studs break.Wheel studs breaking is common among all auto manufacturers you just don't read the other forums.Never heard of wheel studs breaking before this thread?How long have you been on car forums?
The last time I did have studs break at a tire shop was a 2001 Denali I had, and when I changed tires the first time, a kid broke 2 on the right front and 1 on the back right. Of course he swears they were bad before when they rotated them.2 More broke next time I rotated them too,most likely because of him over torqueing. Did I go to a forum writing or even thinking that GM engineers engineered the studs weak on a $65k truck.Not hardly!Not that a big deal.
Most of the guys working in tire shops don't want to break studs so they learn to get off the trigger fast because it's a hassle for them too when they break . A few just don't get it or are new and lay on the whole >500 ft/lbs or more a 1/2 drive impact can deliver.
Worry about broken wheel studs????
Never heard of all of them breaking at the same time and the wheel come off, ever!
Don't sweat the small stuff ,just load the wagon:thumb3:
FWIW...I'm actually agreeing with JED . Maybe we're bonding! LOL

Another broken lug
After warning the technician about this issue, and even referring to this forum, I stood in the bay at Tire Kingdom (grrrrrr!), watched the tech break my lug. I was watching over him as if my life depended on it. I was two feet away from him when he pushed the wrench gently with the palm of his hand...he hadn't even started really tightening it at all...and SNAP! Torque wrench or no torque wrench, that is a defect IMHO. I am positive that I used more force than that on the other wheel when I was on the side of the road an hour before that, and I was using the factory wrench.
I feel 110% positive that this guy did not over tighten it. I am calling my dealer tomorrow to file a complaint to hopefully help the cause to get Toyota to recognize.

That's some serious FUD. I drove around for a week with only 5 bolts, no problem.
Is this an issue that needs fixing? Yes. Will your wheels fall off? Most likely no!
Exactly, most likely no. Possible? HELL YES!!
I can try to dig up some picks of it happening to someone on a Jeep forum I used to frequent.
You think just because they aren't broken, they couldn't have been weakened? Think about it before you call me a liar.
Relax, wheels falling off from broken (or weakened) wheel studs is almost an impossibility. Like any bolt or stud, the wheel studs work because they are under constant tension. Their tensile strength and shear strength are two different things. While it may seem to be relatively easy to snap a wheel stud on your 4Runner with twisting force, that doesn't mean the stud will easily break without applying that twisting force. In other words, even a wheel stud that has been overstretched is still highly unlikely to break while it is holding your wheel on during driving. And even if that happened, all six would have to break before the actual wheel would fall off.

Agreed, however, it is a HUGE pain in the a** when you are on a road trip and they break one in the shop, and then they don't have them on hand and you have to wait for a frekin hour for them to drive around town to all the auto parts stores to get one. I suppose I could have just left that one out and fixed it later, but that is a huge PITA too. I think maybe it would be a good idea to keep some in the truck. What if they had broken four out of 6? Would have saved me a massive amount of time on my trip last weekend.

This will be VERY interesting to see...
I've already replaced 2 broken studs on my 4th gen. I'm actually considering swapping them all out for stronger studs. It's not a difficult job and the studs themselves are pretty inexpensive.
I'm very relaxed...but thanks for asking. I've been working on cars for more than 20 years and I've never once heard of a wheel falling off because all the wheel studs broke. Never once. You have a better chance of the hub separating (due to something like a faulty bearing) than having the wheel studs all snap.
No problem. BTW, I never said it couldn't happen. I just said that I've never seen it happen. Why don't you post up those Jeep links so we can all see for ourselves?

You two should PM eachother...:AK47::gun4:.
Why? I think the link would be interesting for everyone to see. I'd sure like to see it, considering it's something I've never seen before.

Kevin -- Any luck getting this TSB yet?
