Help I snapped a bolt in my hub :/

Have you taken the wheel off to see if there is any thread produting from the hub? Might be enough to get some grips on providing it's slackened off.

Failing that you'd need an EZ out kit
 
Yeh a stud remover is what you need. Failing that you could drill it out and get the thread to collapse on itself.

Either way I'd recommend re-tapping the thread after, you may have caused damage to the thread form.
 
Cheers mate the other 2 wheel nuts were to tight to get off so I thought I would try at work today thanks I'll give that a try
