ABS Tone Ring
I have been having the ABS/ ESP/ Tire pressure warning Message coming up on my dash for the last week.
I have an MB2 Scanner ( worth the $200 I paid for it ) that told me the problem was the right rear speed
of Wheel Axel was off. I had just replaced the Wheel Sensor 3 Months ago and was thinking it might be, I had gotten a Bad Sensor.
It turned out to be the tone ring. Lots of stuff on the web about replacing axels @ big $$$$ and im not saying that might not be the problem for other people.
If you need to replace the Tone Ring the part number from MB is - 230-357-01-82 The picture above is of the Ring that came off my 2007 S550 / 4Matic.
I hope the above helps out if you have a problem like mine.
BTW: The Ring was $22.00 Canadian Dollars.

Just an update:
I have been away with the car and have put 1300 kms on from having the tone ring replaced.
Im happy to report everything is still fine. I Also find the Tone Ring goes by the Name "Reluctor Wheel" just in case you see it listed on the internet with that term being used.
ABS / ESP / TIRE All fine and no Warning Messages in the Dash.

I am not sure about your Torque nut question. may understanding is, all you have to do is roll the knuckle out of the way so you have room to work.
This set up is a lot like the Chrysler 300's

I had my 2007 S550 4Matic in to my local mechanic to have the reluctor ring replaced. He believed he had to remove the reverse torque nuts. None of his tools fit. Do you know if it is a special socket or such, or do you not need to remove the torque nuts? Thanks very much Ed

Hello, I had my car fixed at the local Chrysler Dealership, This system used on the W221 is very close to what was on the Chrysler 300's back in the day.
I still have my W221 and i have not had a problem with it anymore

on 2WD version the front reluctor ring is part of the inner oil seal for the front wheel bearing, its a typical Merc idea. on the 4x4 ones the parts doc doesn't seem to show it

better idea go to the parts dept and ask - the specialists in what bits you can buy and what it is, is the parts guy at your main merc franchised dealership

I'm going to get the knuckle off in the next week or so and I'll post an update with what I find. I didn't drill down very far in trying to get the bits of the speed sensor out, so I really doubt that I damaged the tone ring.

as per post #1 if they used that idea its normal to corrode and fall off
the rear is like that - I wonder if its the same bit for the front ?

I found some pics on benzworld https://www.benzworld.org/threads/4m...s-r-r.1579512/ . I would post them but for some reason, it's not working.
They make the picture much more clear. If I have to press out the bearing, I can get that done at a shop. Thanks for the heads up.

Thanks EasyPhil. Yes, it is a 4Matic and it's the front passenger side where the wheel speed sensor got stuck and broke. I was going to remove the knuckle so that I can clean it out on the workbench. If there's no damage to the ring, then I won't need to replace it, but I was just trying to account for the possibility.
