Jack the car up in the front . Lock the steering wheel . Go to one side and grab the tire/wheel. Try to turn it in and out . Also try up and down( it should not move this way) If worn it will move slightly, if not it will do nothing. You may have worn bearings that will cause vibrations despite having great brakes installed . You May also have end links/ control arm issues. It seems I remember you saying you replaced the control arms for leaky fluid.
Best of luck.
