(G) rear wheel help

hi, went to mechanic out of town, had a puncture, needed a replacement. all seemed fine, until a month later when i tried ot take off the rear wheel to change brake shoes, one of the wheel nut is cross threaded, and sheered off. just want to know what part i need ot look for to fix this problem, whould i be right in orderin a brake drum? (currently running on 3 bolts, is this safe?? MOT due, im guessin it wont pass)
thanks

[i would buy a new set of bolts and drum mate it wont pass mot and is dangerous i had the same prob woth my stilo arbarth and my wheel came off and damaged my suspension aswell as the hub

scrapyard outer drum - £5
job done

thanks!!!
would it be worth while replacing both drums new?
mechanic said before when i bought the car a year ago that there was a lip on them...

What car is it? You need to replace wheel hub, not drums

oh...fiat punto mk1 1999 60s team....was just about to send a scrappie some money...

u sure its the hub???? im pretty sure the wheel screws onto the drum....could check, photo make it easier??

For mk1 you need hub, not drum. I was working on brakes last week on my punto mk1, so I know what I'm talking about . For newer puntos (mk2,...)I'm not sure

ok, ive taken a pic, maybe some mor elight can be shed on this....

been chattin to dad, Could i not just drill it out??

Aye you could but if it's cross threaded your threads will be knackered, and it's dangerous running on 3 nuts, just buy a replacement hub at a scrappie, can't see it costing much, they're about £50 new. Plus you need new nuts.

Of course drilling would be the first thing I'd try to save a bit of money.

gna try drilling out on sunday, purely for experiance, if it fails i got a scrappie holding one for me....

ok....drilling it out...didnt work. was slightly off centre, and bolt is properly in there..not goin anywere. so i guess time to replace hub.

ok peeps, new hub came today, took allot of persuation to get old one off, and likewise to put new one on, but all fitted and done. thanks people!
btw if anyone wants to know,
Rear hub nut is 32mm and 280nm torque
