Boss: <shakes his head some more> "Well, the good news is, you're going to be here all day, and you're only going to make a half-hour on flat rate. Hopefully this will be a painful enough le$$on for you to pay attention. Now, if you'll excuse me, I have to go get bitched out by the customer"

I've broken six studs on this car. I always keep a few spare studs and lug nuts with me. Now I always use anti seize when I reinstall the lugs (despite the torque discrepancy) and I haven't had any problems since.

I should use some anti seize. Never have yet. These tires have been off the hundreds of times.

Some techs are just in a rush to get cars in and out that they aren't careful and DO NOT FOLLOW Toyota Specifications.

I've seen many techs not using the torque stick (which limits it to 70-80 ft/lbs) which causes them to torque lug nuts at 150 ft/lbs (impact gun with no stick straight socket). That's about double the specifications.

Although the techs can mess them up.....I've personally replaced 4 of mine and I don't use an impact gun and I hand start the lugs 3 complete turns. The thread pitch is just too small in my opinion. I'd be willing to bet I've installed more nuts/bolts than 90% of the worlds population and the only time I've destroyed wheel studs is on this car.

CoupedUpSubie · 10-12-2014, 12:22 PM

If any car has been in a shop or at a dealer and the wheels were removed the chances of lug nuts or studs stripping is increased as many over torque them. The torque limiting sticks are garbage. Once threads have been stressed by over torquing there is nothing that can be done. Also torque wrenches need to be calibrated every so often or you can even over torque a nut with those. The only time I have had a problem with 12x1.5 is after 2 or 3 times of a shop over torquing the lug nuts. All subaru's use 12x1.5. Also 1.5 is the standard thread pitch for a 12mm bolt, fine threads would be more of a 1.25.

Have you played with compensating for the anti-seize? I want to start doing this. Still 89 lb-ft?

I haven't broke a stud yet but threads like these scare me. I keep 3 spare studs in my track tool box lol!

I haven't done any compensation. Just 89 lb-ft, and I haven't had any issues with that.

Yeah, it's definitely a shitty problem to have, but if you're prepared then it's really more of an inconvenience than an issue.
