Hello and Welcome to FTE.
Please read and post the codes you get. One thing to look at
is the front wheel plugs. If you look at then and the pins
are green and fuzzy then there is a problem. My right side
will spit out a code every now and then. It seems I have a
bad body side plug.
One thing that can help is a can of contact cleaner and some
dielectric grease. Clean it really well with the spray and then
give it a good glob of grease to keep any moisture out. That
is one thing that drives more truck owners batty than other things.
Good luck. Please post back if you find a fix. You may help someone else.

Please stop wasting your money. Have the ABS system scanned and pull the error codes. That will point you in the direction of the fault.

Earlier you said "all sensors new". Does this mean you changed your right front ABS wheel speed sensor also? If you have, have you checked the wiring to the right front wheel speed sensor for any opens or shorts? Wiggle tests if intermittent?

had to reaplace right hub because bearing was bad left front hub was good but when we scanned we were not getting a reading from the left front so we put a new wheel speed sensor in that hub now we r getting a reading out of that hub but both front wheels are reading 10mph faster than the speedo. the rear sensor is the first one we changed because the scanner said no wheel speed so now we got that one and it is dead on with the speedo and the scanner iam doing all this with the help of a freind that is a ford tech and even he is stumped. we have even taken the new hub we put on and took it back and got a different thinking maybe we got a bad one and put this one on and got the samething we are using a solarus snapon scanner so its a good scanner. just wondering what u guyz think it is before we put a $585.00 abs module on it

DTC C1222 Speed Wheel Mismatch
You might want to pull the new front sensor and look down
the hole and watch it as you roll the hub around. Your looking
for gunk on the tone ring. This is where having an oscilloscope
comes in handy. You can look at the signal from the sensor
to make sure that it's clean and of proper levels.

I think, based on the fact that you got a DTC c1222, and based on you now stating that you replaced the right hub, that the most logical diagnosis is to look at the right wheel speed sensor and wiring. That is what the code indicates, and that was what was moved around as result of the right hub service.
Twice you have pointed out how your rear wheel speed sensor matches your vehicle speed sensor "dead on", but this observation, while comforting, is entirely irrelevant to the DTC code you pulled, and to the 10 mph mismatch your testing found with the front wheel speed sensors.
So it seems logical to look carefully at the front wheel speed sensors and wiring, particularly the right one, first, before throwing a new $585 abs module at it.
