After you start the car & take off the brake pedal starts vibrating & you hear a grinding noise then the ABS light & the TRAC off light comes on & then stays on. We had a couple of Hub assemblies put on the front drivers side but it still does it. Could it be a sensor or something that is falsely activating the ABS? We've fought this problem for a few years now.Please help!!!

Start by having the codes checked, you will need a chassis scanner or a garage that has one.

But if you hear a grinding noise, it is most likely mechanical (rotors, pads, calipers) than electronic.
