w210 broken ABS sensor ring

[Zacharias]

Right rear ABS sensor ring is broken.

As those of you who have seen this happen know, it causes all manner of intermittent problems with drivability.

Unfortunately Easter is a 4 day holiday for many businesses in this part of Canada, including parts warehouses and vendors. So I can't do much of anything about it until Tuesday now.

Questions:
1. Is the ring available as a stand alone part? I see it in Europe in the aftermarket. Not here.
2. Is it just better to change out,the entire axle?
3. Why does no one seem to list rear axles on the parts sites?
4. My mechanic pulled the main fuse for the traction control in the hopwsnit would help, and told me to switch off the TC as well. The fuse hasn't made any difference, and turning off the TC via the console switch made the car undrivable.

Any advice on any if this? Thanks.
