how to tell if 4 wheel abs 2001 4x4

[Chamberlain79]

I have a bad drivers front wheel bearing i already have it took apart. I call the parts store and they all ask me if it is a 4 wheel abs truck. If it is 4 wheel abs will it have a sensor wire in the back ? How do I tell What i have ? Their is a big difference in price from one to the other. It is a 2001 4x4 f-250 with a wheel disk brakes.

Yes you will see a small sensor on the top of the outer knuckle that has a wire running off of it. JJ
