Yea, this is good info. And I will no doubt address it too.
I think that dawniewest is dead on with "Just driving had caused it to loosen over the past 2 years"
So it is likely that our brand new DRY 213's are no guarantee that we do not have the same potential issues to avoid. But then, I don't think it is a 213 specific concern either.
