Wheel Bearing CLUNKING ???

Why would a lower ball joint make a sound that corresponds to the revolutions of the wheel, that literally "knocks" in perfect rhythm...........?.....especially when the lowers seem nice and tight?.............

Seems if it were a lower, it would be nearly falling out of the car........But it's not.......the idler and pitman both have some play, and too much, believe me.........they're being changed........parts just arrived........but I've never heard them make this kind of noise on an old car, regardless of wear..........

Time will tell I guess........I'm havin' my mechanic tear it apart on Monday morning when they change out the pitman and idler............

........I'll let ya's know exactly what it is.........(besides annoying and a bit scary) :clock:
