Help with an ABS issue!
I have a 1999 Ranger Super Cab 4x4 XLT with a 3.0 flex fuel that is having some ABS issues. When the brakes are applied and I am slowing down and get to about 2-4 MPH the ABS kicks on. I scanned the truck with a Ford scan tool and while driving it told me that the front right wheel speed sensor was off by a couple MPH. I replaced the wheel speed sensor and indeed the old one had a broken coil. After replacing the wheel speed sensor the truck still has the same symptoms. Anyone else have this issue? ABS kicking on around 2-4 miles per hour when braking?

That wont fix it. Its your rear tire locking up. mine does it all the time. its pretty embarrassing when im going like 2mph and i hit the brake and they lock up and let off, abs light flashing lol. i got used to it. not a big deal man. the light should go away or u can spray it with wd40 (the sensor)

My truck did the same thing when i switched to aftermarket rotors. It turned out the tone ring (that the ABS sensor uses on the backside of the rotor) was slightly different than the stock one. Have you recently replaced the rotors? I would check the tone rings to see if they are wobbly cause that might throw it off.

Check here for a little info .

Also jack up the front wheel and check for a loose wheel bearing.
Click on the Search button at the top of this page and type abs 5mph in the keywords box.Then search. That narrowed down the amount of posts to wade through.

I am thinking it is the ABS module. I have checked resistances, voltages, used a pico scope, ford scan tool, and an OBD2 scan tool. All are within spec and the sensors are sending signals which are pretty accurate. Mounting surfaces are clean, and the tone rings are clean. Not sure where else to go from here.

so what were your guys' fixes for this issue? My abs comes on mostly when I slow down and turn right, like into my driveway. I ended up replacing (because they broke getting them out) the rear and front drivers side speed sensor to no avail. My luck would say that the passenger front is bad. I don't really want to try and pull it out because it'll prolly break too, but could that one be the culprit?
