I recently had these loosen up on me and one of them broke off. I can get the broken one to turn with an EZ out but it refuses to come out of the hub due to screwed up threads. What are the odds of catostrophic failure if I just run for a wheeling trip w/o one stud? I would normally replace it but am having a hard time finding one in time for the fundraiser I am attending next week.

Thanks!
