Tire Stud Snapped Off, Help Needed!

[EddieV4runnin]

Sounds to me like you know how the operations of America’s Tire Corporation is conducted. Must be from all of that time in the automotive service and repair business. Smh *

a wise guy hey

I have put 45k on my 4Runner and I have gone through more studs than I care to count. Probably 8-10. I did realize the place I bought my tires was torquing them down to 100. They also had free rotates and almost every time I went in they would snap one or two. Finally yelled at the manager after waiting 2 hours for a rotate and balance because they kept having to have studs delivered. They always fixed it but now I just go to Toyota. Seems like they do not like to be over torqued at all.

Most places will hand torque it if you ask them too.

Annnnnnnd the tire shop just snapped one of my studs. I had read this thread a few days ago so I was careful to use ~83 ft/lbs when I put my wheels back on after I installed my lift. The funny thing about this, I was watching the guy tighten the nuts with a torque wrench as he got the uh-oh look on his face. The shop is taking care of it but it's making me curious if it's a quality control issue with Toyota. My rig has less than 400 miles on it.
¯\_(ツ)_/¯

OP, the exact same thing happened to me at 200 miles at Americas Tire. They reimbursed me for the dealership fix. Since that incident I have come to appreciate that Toyota is using low strength bolting and it will easily break if you side load it like when starting to torque but the lug nut isnt yet centered in the hole.

Check out summitracing.com for high strength lugs. The Lexus I3 300 is the correct knurl diameter but the underhead length is too long. I replaced all my front lugs with these (ARP 100-7715) but had to cut them down which was a pain. I actually did all this primarily because my FN wheels only left me with 4.5 turns of thread engagement and I was paranoid. Cut to 1.90" for 11 threads engaged. The rear I did not change as they had 8.5 threads and it is hard to change the lugs due to the e-brake drum setup.

Hey all, first post here but a long time member on the Taco and FJ forums...

The FJ's are known for stretched and snapped wheel studs - I've had to have a few replaced myself, and one very prominent member (FJoel) had all 6 shear off while driving even! He is a machinist and sells ARP wheel studs that he shortens to the correct length for the FJ (ARP doesn't make a direct replacement). I would suspect that the same is true for the 4R, since it's pretty much the same chassis - cheap Chinese pot metal I'd guess.

Also, just FYI, Toyota's torque spec when you have aluminum wheels is 76 ft - lbs. I've learned to rotate myself and check torque every time I check air pressure, which is often.

Cheers, nice community you've all got here!
