Asking a tech would be pointless unless you have a really good tech or a really good relationship with that tech. With most, their answer would vary according to whether or not it was good paying work or not. You'll get a different answer if it is warranty work. If DC refuses to pay for an alignment, woe unto the tech who says it is necessary. If the vehicle was aligned while the ball joints were worn, it may well need an alignment. If the joints weren't that worn, or the alignment had never been adjusted to compensate for wear, then you probably wouldn't need an alignment after joint replacement. It all hinges on how worn the joint was. Mine were replaced at about 15k. No alignment needed, but the joints weren't worn either. The alignment hadn't been touched. If a worn ball joint could keep the proper relationship between its upper and lower portions, there would be no reason to replace it. The recall is driven by the fact that the joints can wear to the point that they separate. A part that is worn that badly can't be keeping everything in its proper place. If the vehicle has been aligned to compensate for worn joints, it is in a two wrongs making a right kind of place. If you take away one of the wrongs, the math no longer works.
You backed up my statement. The ball joint by itself doesn't change alignment. Get a tech you know and trust. You will be the benefactor of the relationship.
