I had similar issue but with top control arms. If ball joints truly worn out, you can grab tire (car off ground) at 3-9 o'clock or 12-6 o'clock position and push-pull. Tire/wheel will be loose and will move. With upper ball joints, you must replace entire control arm (labor won't be any more; in fact, may be cheaper). Don't know if same with lower. Must replace both sides even if only one bad. And do need 4-wheel alignment after repair.
