Speed sensor
 

Has anybody had to replace a speed sensor in their JK yet? If so how involved is it...can I do it or should I take it to dealership?

I did them on a mercury mountaineer. Very easy EXCEPT they sometimes have a tendency to break off at the hub. There was a thread on here a month or so ago about this issue. I would advise to spray the area with PB blaster a little while before trying to remove the sensor from the hub. Then, wiggle the sensor while pulling to try to keep it from breaking off inside.

easy to replace. I would spray some PB blaster or something like that on them to help ease them out, they can be a little fragile.

Thanks guys
