Replace ABS tone sensor ring

[todda7]

The ABS on my car kicks in at low speeds, and I was pondering whether or not it was the ABS sensor, the sensor ring or a bad solder job I did on the ABS wiring some years ago. I took a look at the CV joint and low and behold, the sensor tone ring was cracked so I assume this is the cause for the ABS kicking in.

Has anyone tried replacing the ABS/Wheel speed tone ring? It looks like this:

I don't know if it can be done without replacing the hole CV joint, but I would rather not replace the whole joint.
