Turn up the radio and go with it. It's fine. If it really bothers you too much before you're able to to do the fix, get you some good automotive silicone. Get the type that dries plyable, not the type that dries solid. Get in there where the little ball end piece fits into where the bushings were and gob it up really good. Once it dries it will still function, but will absorb alot of the friction that makes the knock. It's temporary but will quiet it down until you get the kit to fix it.
