i rotated my tires about a week ago and i twisted off two wheel studs. I was only torqueing them to 85 lbs an they just gave away. I was just wanting to see if anybody else has had this problem?
the previous owner could of over torqued them, or maybe the tire guy oever torqued them when i bought new tires.
i just had them all replaced an it cost $400.
any input would be appreciated.
Thank, Tedrow
i just busted one off of my sequoia last week. i didn't use a torque wrench, but i've always tightened the last 1/8th turn with a slight step on the lug wrench on all of my previous rides and never snapped one off. my dealership said that it wasn't covered under warranty because it is a breakable item. the cost to replace one was $110.

This is regretable. However, wheel studs are inexpensive themselves, and are easy to change. Maybe you could do it yourself.
While 83 ft./lbs. is the correct torque setting, and depending on your size, you could easily apply over 300 ft./lbs. torque to the stud if you put your weight on the lug wrench and bounced or shifted your weight up and down even slightly. To prove this, get one of those torque wrenches that clicks when the specified torque is reached, set it to its highest setting (about 250 ft./lbs. for a 1/2" drive unit), put it on a bolt somewhere convenient, put your weight on the handle carefully, and then bounce ever so gently. This will demonstrate how easy it is to over torque your wheel nuts. I have no doubt that any average male, and a good number of average females, could easily apply over 200 ft./lbs torque to a wheel nut with a T-wrench, using their arms only, and a little technique. Grab the T-wrench by its opposit ends and level to the ground, keep your elbows straight, and tilt your body in the direction of the turn while keeping your upper body and arms stiff. See, over 200 ft./lbs. and almost no effort. Without a torque wrench, you really are guessing at best whether your wheel nuts are tight enough, or whether they are over tightened to the point of damage. Worst of all would be where the stud is cracked, but not yet completely broken; now, just where and when will that one fail? I sincerely hope this helps eveyone.
i am definitely going to invest in a torque wrench after this experience. i've always known that it was a big no-no to lean on the wrench, but i've been changing tires since i was kid (when my weight would barely turn the wrench), so old habits are hard to break. i was concerned about the rest of the wheel studs as well, but the dealership inspected all of the wheel studs and retorqued them, so i should be okay. again thanks for the heads up! looks like i'll be heading out to sears.
when i torqued them i wouldn't think that 2 lbs difference wouldn't matter. i have changed tires on my 95 talon an did them to 90 lbs an never had any probs.
but does toyota use a lesser grade stud where it should of been a higher grade??? i love my tundra an wouldnt trade it for nothin.. just so anyone thinks that i hate my truck, i dont.
but with aluminum rims on my talon i even had one wheel work loose on it an had to retighten it.
i just thought i would ask to see if anyone else had a problem too?
thanks for the replies.

Dont know what to think----I have never in my life had a stud break on ANY vehicle I have ever owned. I have changed my own tires, I have had shops do the work . Never a problem. I have had shops tighten the studs so tight that I would have to use a pc of pipe as a cheater to break them loose. Never had one break. This bothers me that the studs are breaking on these trucks. Are the studs inferior? Are other vehicles having the same problem or is this just a Tundra or Toyota problem?-------Buzzard

Just what the heck on these trucks is NOT a breakable item.
Assuming your vehicle is still in warranty, and that "abuse" isn't being raised, the hub stud should be covered under warranty.
If your dealer disagrees, ask for the District Service Manager or even the Regional Service Manager, they are the referee. Though 3rd hand, I know people who have had hub studs warranted.
Bill R's analysis is correct.
Another item, what was the condition of the thread? Wheel studs should not have any lubricant or oily residue on them. That changes (lowers) the coefficient of friction and for a given torque, the bolt is in greater tension. This could lead to tensile overload.
I've heard talk of individuals using anti-seize with Aluminum wheels, definitely a potential problem.
If you have aftermarket wheels, the mating surface coeff. of friction may be different, but that shouldn't be enough to matter.
Regarding Toyota hub studs, its likely a common part to Tacoma, FourRunner, etc. so I doubt they're inferior (i.e. it'd be bigger problem). Toyota only has a few p/n for hub studs.

And it's certainly not a wear item. It broke during normal Toyota recommended maintenance. It's on their shoulders to prove you you broke it due to misuse, modification, etc.
i hear ya! i knew i could do it myself, but i had to get it done right away, had a long distance trip the day after. i haven't had time to call the service manager, but when i get a chance i'm going to try to get a refund for the $110. they know that i usually have 20" rims on my ride, so they might use that against me. well, i'll see what happens.
$400 to replace 2 wheel studs!
When i had my wheel locks removed, they told me that they would charge me $20 and extra $20 if they had to drill out the old studs and install new ones.
I had one break off on my 01 when I was removing a front wheel. Before taking the wheel off Discount tire had previously done a rotation so when it broke I took it to Toyota who charge $50.00 to replace it, I then took the bill to Discount and told them it broke off due to technicians cross threading the lug which was true. I was re-emburshed and it worked out great!

it also could of been a simple mistake as cross threaded the lug nuts. very easy to do if your not careful, especially on big tires which the tundrs has.
i've applied 100 ft/lb to my tacoma and it didnt even come close to breaking, just torque in a criss-cross pattern and done, and about those wheel studs
Come guys, damn i did it myself for $5, go buy it at any auto parts store, ask for a wheel stud for the truck its for, a new lug nut and like 3 or 4 washers. just hammer out the old stud.
Then put the new stud in place of the old one, put the washers on it and screw in the lug nut and with an air gun tighten it and thats it, depending if its the rear or the front, you have to take the drum off or the rotor, thats all there is to it? i feel bad for those guys who forked over hundreds of dollars.
and those mechanics, easy money for them, so they take advantage
