W126 ABS light & wheel bearing clearance

[Two560Two]

Ever since I replaced the front pads, rotors, inner and outter wheel bearings and races, the ABS started to act up. I tightned the wheel bearings by hand without using a dial indicator just enough to have little play but tight. The ABS seems to activate during normal braking up until 30 mph then the light stays on until the next key cycle. I rechecked everything, the sensors which look ok, the tone rings which got some bearing grease on them but I cleaned it off completely with shop air and brake kleen. I repacked the bearings again still with the same results. Anyone ever have issues like this? I am thinking the bearings clearance are way off causing this to happen
