June 21, 2010On a 2003 F250 Lariat 7.3 Is the ABS system on all 4 wheels or just the rear wheels?
June 22, 2010on my 2003 F250 5.4L gas engine... it has abs on the rear and the front.
see if you have speed sensors on the front wheels, if so then there is likely ABS up there too.
may I ask why this question?
June 22, 20104 wheel ABS systems operate in a three channel or four channel system, depending on the manufacturer and the model.
June 22, 2010well I am 99% sure the ford pickups are three channel systems where the rear brakes are treated as one.
And the front wheels are treated individually.
How do I know this? Cause the rear wheels do not have individual speed sensors, only the main tone ring on the axle.
