Hey Shaun,
What kind of heat source do you recommend? ... I have very little space to work with, since I don't have jackstands. I am using 2 ramps that lift the front only ... To make things worse, the nut is now worn out because of all the force I was trying to put onto it, so I probably need pliers to do the job ... which makes it even harder. My sensor is basically broken into pieces

but i couldn't get that damn nut off
