I bought a new CV axle, but I do not see anywhere on the new axle the new abs reluctor. They told me that it is supposed to come with it and also Ford says in there picture that it is not showing the new tone ring in the picture when they pull up a new CV axle. Is it a sealed ring or because Ford says they does not sell individual abs reluctors.
Do you
have the same problem?

The tone ring does not look like the normal toothed ring. It is a smooth metal disc that is pressed onto the outer CV joint housing. It can be transferred from the old joint. You can find a replacement on the Rock Auto web site.

Wait so please tell me I did not return a the axle when I actually need it, but why did Ford say that the axle does not come with it? That I just ordered a new tone ring that has the teeth on it, because the teeth can be seen on the car if you remove the ABS sensor and look in the hole. So if there is no longer a toothed ring how does this new part compare?

Those are questions for the people in the dealer's parts department. I looked the part up on the Rock Auto site and found it looks nothing like what a normal tone ring looks like. GM has used a number of tiny stamped metal discs inside their wheel bearing assemblies, that do a pretty poor job and provide real wimpy signals, but they do work when they are new. I am guessing your ring is of a similar design. Unfortunately they only show one view of it.

With the more common cast iron toothed rings, those can be tapped off an old joint, then glued on to replace a cracked or missing ring. You cannot usually buy new replacements, but the salvage yards are full of them. They have barrels full of "core" half shafts that will be sold to rebuilding companies. You should be able to get a tone ring off one of those for a couple of bucks.

So in other words Ford changed the design from toothed to that new style? Cause right now I got toothed on the car an recently had new bearings installed
and the passenger side is giving me trouble now, because I have ABS lig, c1234 and c1236.

Was there a toothed ring on the old shaft? If there was, you need to order a replacement shaft specified for anti-lock brakes. I looked through all the choices and did not see any that showed that common type of ring. They only showed the metal disc.

I just went through dozens of pages in the service manual, and there is no reference to or drawings of the tone ring. At this point you know more about what it looks like than I do. You might consider visiting a pick-your-own-parts salvage yard to see what is on a similar car. Do a search for "Pull-A-Part" and see if there is a yard near you. I have been to sixteen of them. All are very clean and well-organized. Parts are cheap, and the people have always been very friendly and helpful.

This is where you need to talk with the people in the dealer's parts department. Ford is also famous for making major mid-year changes. When that is an issue, the people looking up a part for you will ask for the car's production date. That is found on the sticker by the driver's door.

I haven't been able to find any drawing or photo of the tone ring you're describing. That is very odd.

As a point of interest, the fault codes you listed refer to missing wheel speed signals. If the tone rings are the cause, those problems will not be detected until the car is moving, sometimes as much as a few yards up to a mile or more. If this were due to an electrical problem, as in a cut wire to a sensor, that would be detected as soon as you turned on the ignition switch and the ABS Computer went through its six-second self test. The yellow warning light would stay on, even before the car was moving.

Is there any chance you could post a photo of the shaft with the ring on it?

So turns out I am unsure whether or not my 2004 Ford Focus has a tone ring with teeth or if it's the other kind that you had told Nebraska about, so let me understand this, if I buy a brand new axel as you say it has a different style tone ring, would I be fine? I've tried everywhere and cannot fjnd anything I've tried all the part stores but

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.
