Just had both the lower control arm and the thrust arm replaced because something was thumping at low speed when the brakes were applied. The drivers side front wheel is moving back and forth when I hit the brakes. Can make it do it in the driveway. I thought for sure it was that thrust control arm but it's still doing it after I replaced both parts with new. BMW tech says it might be the swap bar links needs replacing but I don't think that would make the wheel move back and forth on braking. Any ideas?
