Eh, all depends if they were torqued near the yield point. What were tehy torqued to? Were they run with a impact? then torqued with a wrench? That joint is not one that can get to its yield point very easily, it takes a lot to get it to yield. What is teh thread size? and what is the dia of the bolt I can give you a approx yield point
Hockster has the right idea. The joint is pretty robust.... It'll be alright and have no problems getting to the event. But I would fix it before I start goin balls to the walls. If all else fails, a new set will run you probably less than 50 bucks.
