    Cross threaded hub...

    Need some help...

    2 weeks ago I had some tyres balanced and fitted on my second set of rims by a local tyre shop. Between now and then, no one has touched my wheels. I tried to take off my rims tonight to inspect my brake pads but the bolts were TIGHT.

    I could barely get them to loosen without using all my body weight and more - I've rotated and replaced my rims countless times and never have my bolts been this tight. I've always torqued them up to spec and always been able to loosen them without excessive force.

    Thinking back, I'm 100% positive that the mechanic used an impact wrench to put the lug bolts on and then proceeded to further tighten the bolts using his entire 100kg body weight

    Anyway, I discovered that one of the bolts has been cross threaded. I had no option but to keep loosening it - I am now down one lug bolt and have some mangled threads in one of the holes.

    What do you guys think I should do? I don't see how I could've cross threaded the bolt by loosening it, the bolt was so tight I suspect it was already cross threaded.

    I was going to contact the shop tomorrow morning and explain that no one has touched my wheels since they did and see what they have to say. I was also considering getting a m14x1.5 tap and trying to chase the threads from the other side...I've done this before on some other bolt holes (not wheel hubs) with success but not sure how well it will work with a hub...

    I don't want to buy a new hub just because of a stupid tyre fitter, besides, I need the cash as my downpipe is absolutely broken at the flange due to some track thrashing

    Thoughts???

    That's really bad - I wonder if they can use some sort of thread insert to fix it

    I once snapped a wheel bolt that had been gorillad by a tyre fitter

    I know I will sound pedantic, but when it comes to tyre fitters I always tell them to hand tight it. I don't care, I will stand there and watch them do it, and if I really feel they will make a mess of it, I'll do it myself.

    Better safe than sorry I guess. Sorry to hear.

    What the F happened to torque wrenches?????? dear oh dear i have 1/4 to 3/4 in my van man. Back in my Porsche days with magnesium nuts etc you never heard impact wrenches in the wshop. Torque it up and thats it, they have impact guns with torque bars now which are pretty good and i took a a fair but of convincing but anyway , no need for jumping on lugnuts serious lack of knowledge which itself is dangerous. Sorry to hear that mate but annoying at the same time

    Cheers

    Big shoutout to Dean @ Volkspower, repaired the hub for free whilst getting my minor service done! Drilled out the hole, inserted a helicoil and problem solved!
