I'm thinking that the speed sensors are on external brackets, and the tone rings are on the CV shafts, not inside the hubs.
MAYBE the sensor brackets are bent, so that the sensor is too far from the tone wheel. Worth checking.
Beyond that, I've had multiple vehicles where the wire harness is either outright damaged--torn, insulation worn through--or the conductors inside the insulation have corroded. Check the harness carefully.
