how bad will replacing it be if it's not a good one? Combined with alignment cost, might not be a place to skimp... Never had problems with rebuilts before though, but, there's always a chance. Check the condition of all threads. Not sure what items are wear items other then a few seals, how can that be screwed up at a rebuilding shop?
