Garage Cabinets, Garage Storage, and Garage Organization

Hi everyone here,
few days ago i was driving my E320 down the highway and it starts making this strange rubbing noise from the drivers sidefront. i've replaced- the wheel bearing, whole shaft(both cv joints), and last night i swapped transmissions thinking it was the differential bearing. the only thing left is the ball joint but that would make a rubbing sound.
someone please help!!!

thanks for time

hi...
do check on the splash guard around disk,may be rubbing somewhere.otherwise check pads are located correctly, and check whether shims/springs in alignment or out of allignment.
