I have been tryin to get out and get some pics of how to remove the sensors. It has been raining here like crazy and it seems like every time I try to get out and do some pics I get pulled in 4 different directions. I will get a detailed how to done shortly.
I am not sure on the clicking sounds.... I will give it a listen and try mine.
As far as the front sensors, I got the center one out without removing the bumber... the sensors on the sides I know are different. The have a 90 degree bend in the connection so I stayed clear of those.
I should have something written up by this weekend
