I have a 97 F-150 4x4. I need to put a new wheel bearing in the front and the shop needs to know if it has 4 wheel ABS or not. I don't see any wires going to the front rotors, but then again I don't see wires going to the rear drum either and I believe rear ABS was standard. I know this is a dumb question, but I bought it used and have no idea if it has that option. Is there a number in the VIN that will tell me? Thanks

 

the rear abs goes into your diff the tone ring is bolted to the ring gear if there is no tone ring on the front wheels and no wirers then you do not have front abs

 

a wire will be clipped to the front brake hoses if you have front abs.
Here you can see the wire in the loom above the front shock.
