Don't know on the TPS but the hum is probably ring gear-pinion noise--out of tolarence--might also be a rear wheel bearing--after driving it some distance at highway speeds, stop and slide under the car and feel both sides near backing plates--feel center section--should be warm but not hot--be-careful no telling how hot they might be---bobr19
