Rear speed sensor removal... help!

I've noticed that a lot of people have had problems with the t/c and ABS lights. Mine went on and off for a while and now they're stuck on, and I've determined the problem to be the right rear speed sensor. Apparently sometimes it's not busted, it's just dirty or un aligned. I took the wheel off and had a look at it but I couldn't figure out how to take it off, and I wasn't about to pull the hub off to try and figure it out. Has anybody taken one off of re-aligned one? I want to try and get it to work with out buying a new one!!

There's an 8mm (maybe 9 or 10) hex head bolt (back side of backing plate), and the sensor will come right out.
^^^Clean it, and see if that cures the problem.

The tone ring itself can't be removed unless you pull the hub off:

Turns out you just have to pull harder. There was no problem with the sensor, it was the wiring harness up the frame a bit... just spliced new wire in and T/C ans ABS are back in action! Now I can pull the fuse to disable them again, I just like to know things work... even if it did take a year before I fixed it.
