My ABS light stays on. So far I have done the following to my van. Replaced the tone ring, replaced the front disc brake pads on both sides, Replaced the front shocks /struts both sides. Check to see if there was enough brake fluid in there. I have bought a replacement connector that goes on top of the axle that connects the ABS sensor to the rear (picture of it below). But I cannot for the life of me to get anybody to replace this part for me for some strange reason. Well that's all I can remember that I have done to it so far. So far I haven't checked to see if the ball bearings are bad, because I don't have a working jack at the moment.

It could be the wheel speed sensors, ABS module, rear speed sensors are a few other items. The first step would be to scan the vehicle and see what code(s) are in the system. Without that you could replace every part and still have the light on because it is something else. Because it's a Ford I would suggest getting a copy of FORScan and the correct dongle That will give you a tool that can do as much as the OE diagnostic system but for a much lower price, and it works on pretty much all the Ford makes and even on some Mazda vehicles.

Or get one of the handheld units that can read ABS codes.

Then use the codes to give you a map of where to start looking.

This guide can help as well:

https://www.2carpros.com/articles/7-common-symptoms-of-a-bad-automotive-bearing-hub

Which tells why the bearing hub can cause this problem, but like Steve W says we need the codes to see what's going on.

Here are the ABS system wiring diagrams so you can see how the system works. I would also check the fuses and grounds of the system which I have included as well. Check out the images (below). Please upload pictures or videos in your response to the problem so we can see what's going on.

Hello guys (Steve W.) Okay, I will see if I can get it scanned once again. And see what codes it is pulling up this time. If I remember correctly I think someone on here told me that my van has only 3 speed sensors. 2 in the front and one in the center of the axle in the back. And thank you Ken for another awesome guide and wire diagram. Hopefully this will pinpoint what the problem is. Wow, I haven't ever seen a wire diagram like that before. I had no idea my van had this hidden inside of it. Also, now the ABS light will come on and go off. It's like it has a mind of its own now. This is so frustrating etc. Anyway, I will keep you guys updated.

The scan will help tell us which sensor is having an issue.

Here is a guide to help you test the sensors manually which could help:
