You have us just as confused as you are. You're saying you can see that the tone ring has teeth on it, but you can't find the tone ring. That doesn't make sense.
There is very little information on your anti-lock system, which is why we can't look at a drawing to determine where the tone ring is. If it's built into the wheel bearing, like on the very poor design GM uses, you'll never see it. If it's pressed onto the back of the bearing assembly, it may be necessary to remove the assembly to see it, but you could be shown it on a new one at a parts store. If it's pressed onto the CV joint, you should be able to see it on the car, but you might have to look underneath from various angles. You should be able to see what the sensor is looking at when you remove that sensor and look into the hole.
As for pictures on the box the half shaft comes in, that is a photo used to show the type of part in that box, not the actual part. 50 different car models will use 50 different-looking half shafts, but all 50 boxes will have the same photo. If that photo includes a toothed tone ring, that is simply a photo of the most common design.
I see from your other post that this all started when some brake work was done. At that point you should have turned around and gone right back to that shop. All brake work warrants a test-drive, and the mechanic should have seen the yellow ABS warning light was on. It would have been obvious the cause was related to the replacement parts, and he is obligated to correct the mistake. No shop owner would open them self up to a lawsuit by leaving a safety system non-functional. Once you started trying to solve this on your own, you took on the liability and released the shop from their responsibility. With so little printed service information to look at, I would have to compare the new parts to the old parts to see what is causing the problem. I could be incorrectly telling you to buy a separate tone ring. The one part I found called a "tone ring" could easily be a mislabeled "tone ring cover" or "tone ring shield". If this were a Chrysler or GM vehicle, there is all kinds of detailed service information, plus, their systems were perfected many years ago and have been used over and over on most models. We don't even have to look up any service information because we have it memorized. Your car apparently uses something different. Why Ford is keeping that detailed information secret, I don't know. That's why I still recommend taking a similar car apart at a pick-your-own-parts salvage yard. I do that quite often when I want to learn how something works.
