Already talked to Robbie, hope to find a time this week to take care of it. After wrestling all weekend with the rear knock sensor that is a few inches away from the PHH, I am glad I am not tackling this myself. I have rather large forearms and hands, and I am pretty bruised and cut up. And I STILL don't have the knock sensor out yet. Grrr....only 3 trips to Sears to find the right socket size.
