JamieP Posted January 21, 2007 Share Posted January 21, 2007 Pic says it all really, snapped four of the five studs on my way to basingstoke meet, luckly i got to a mates house and we went hunting for some new studs. Went in a small parts shop and a customer over heard me asking for the studs, shopkeeper never had any but this guy said he thinks he does and do i want to follow him back to his house Result he had the perfect ones, hour later i was back on the rd and off to basingstoke meet:D Im pretty shaw i know the cause of these snapping but ill keep that one to myself:D Quote Link to comment Share on other sites More sharing options...

JamieP Posted January 21, 2007 Author Share Posted January 21, 2007 Ok ill come clean... last weekend i was doing a bit of showing of at TF as ya do and i lost it, went backwards up a curb. All seemed fine but i must have stressed the studs. Quote Link to comment Share on other sites More sharing options...
Daston Posted January 21, 2007 Share Posted January 21, 2007 bloody hell you were lucky mate could have been a write off waiting to happen! How did you get the broken studs out? Quote Link to comment Share on other sites More sharing options...
JamieP Posted January 21, 2007 Author Share Posted January 21, 2007 bloody hell you were lucky mate could have been a write off waiting to happen! How did you get the broken studs out? There easy to get out, there on a spline so just banged them out with a hammer and punch. Quote Link to comment Share on other sites More sharing options...

All seemed fine but i must have stressed the studs. It's still comes down to the torque setting. 4 out of five studs failing at the same time?!!! The 5 studs when torqued correctly should exert sufficient force to ensure there is no relative movement between the wheel and hub. The roughness of the two contact surfaces determines the friction of the joint. Your failure is classic incorrect torque tightening. Probably too allow low a setting if you are certain the bump was the event when they all failed. Too high a setting and the studs stretch plastically (Hookes Law) but don't reduce load as long as they don't reach the yield point. Ideally any stud/bolt should be torqued to induce enough tensile load to keep it on the elastic range. Apologies for being too technical - it's what I do for a living.

I cant see it being anything to do with torque settings, although i am a bit heavy handed sometimes, i can see where they spilt half way through a while ago as there rusted that bit. Either way all sorted now but im gonna change the lot next week to be on the safe side. Quote Link to comment Share on other sites More sharing options...

Chewie Posted January 21, 2007 Share Posted January 21, 2007 i can see where they split half way through a while ago as there rusted that bit. And what do you think caused the splits? It's definitely a torque setting issue. Use a calibrated torque wrench or start buying studs in bulk. Quote Link to comment Share on other sites More sharing options...
JamieP Posted January 21, 2007 Author Share Posted January 21, 2007 And what do you think caused the splits? Well ive never had a problem till last time i drove it i went backwards up a curb at 20mph... coincidence??? i dont think so. Quote Link to comment Share on other sites More sharing options...

I'm struggling on the bit I've bold/italic'd above, but are you saying that if they're not torqued-up tight enough, then a bang/kerb mounting like what happened could cause them to fail in the way they did?
