Removal and installation of a reluctor or pulse ring is straightforward but requires special tools that your local automotive supply house will not have. I've attached a few figures to give you a better visual idea of what you are dealing with. Figure 1 shows the rear axle shaft that will need to be removed. You will then clamp the axle shaft into a vice using clamping jaws (see Figure 2). You remove the pulse or reluctor ring from the external joint of the axle using a special tool. You should clean up the axle area and install your new ring being careful not to damage it (no magnets or screwdrivers near surface). You then reinstall the axle and test. This is a simple overview but gives you an idea of the work involved. You may want to get a dealer or Indy estimate to perform the work before you start looking for tools. Also, it would be advisable to further research this work by buying the EPC/WIS software and/or using the Internet (e.g., YouTube) to look for additional information. Good luck getting your reluctor ring replaced and your ESP function working properly again.

 

1st image number 5 has to be undone from the wheel carrier. 2nd image shows it all...

 

I had the same problem just changed 2 rings rear and problem solved light off car out from limp mode , but you have to check SBC too if you have problem with it might come back again , on my car 2 days ago I changed 2 front tires cuz I have winter tire , light came back again when I put scanner says 1 or more speed sensor . yet I don't know why

 

Forgot to tell you about C246F that code mean your SBC life 0% !! and I bit you have service brake Vist workshop on dash in that case either you replace SBC or rest it with tool from ebay @ your own risk if you rest it and SBC have problem you might loose brake @ any time you driving the car my advice if you really wanna keep the car Replace your SBC PUMP ..

 

I had to finalny do my other side and run into an interesting issue. When I cleaned up the CV joint ( and as you can see it was bad), the old ring was still there and it didnt look like it was. So I tried to install the new one and it obviously would not fit. I'm attaching an image what it looks like without the reluctor pulse ring for reference.
What I found troubling is that the joint is throwing small amount of grease not from the boot but what appears to is metal junction of the CV cup. Will monitor...

 

Had to tackle this job on my GFs w204 yesterday.

Since MB deleted the inner driveshaft hub bolts you must therefore remove the hub. What a PITA.

Slotted the old ring with a dremel nearly all the way through then cracked it with a cold chisel to remove remains. Clean shaft with wire brush in a drill, smear of locktite and wooden drift to install new ring. Thankfully they are available from MB and inexpensive which sure beats having to buy the whole driveshaft! I imagine the other side is in the same state but is still working

 

Where are you ordering the ring from?

Hi. Is there a special procedure to reinstall the wheel carrier? I am struggling to get the lower control arm bushing into the wheel carrier. Thanks, Max

 

There’s a tool that presses the bushing into the carrier as you tighten a lead screw. The MB tool is sized precisely but you might be able to cobble something with a generic bushing press set.
