Quick question re Magnum Wagon

Yes, vehicle speed sensor, a scan tool would be essential here, to view live data with the vehicle running and driving, otherwise it's a throw parts at it deal till you luck into the cause.
I have a Blue point Microscanner, will have to figure out how to use it while running though! I have replaced all 4 hubs/tone rings so far. When i reset all the codes it stays clear while running (parked) until i move 50 feet. Then instantly stuck in limp home and consistently throws:

U140C
U140B
P0501
P0700

and ABS codes
C102A
C1035
C1042
C121A
C2100

Did I mention I hate computers....?
