Ok, I went to change my ABS sensor on the rear differential of my 1997. The darn thing was in their tight and I figured I'd try to give it a twist to help break the seal..well the thing broke off in there right below the plate to screw it to the housing. So what do I do now..any advice?

Edit* I guess it is technically the speed sensor.

 

Never done it but perhaps if you remove the cover you might be able to pound it out with a long bar.

 

That's what I was thinking. I just wanted to check first for any other ideas before cracking the diff cover.
