This is odd. My Civic, when very slowly rolling, like in a parking lot, not even a speed of any kind registering on the speedo, has a noticable dip or bump or something on one of the rear tire/wheel areas. It is as I described it in the title, like a limp. You can count one thousand one, one thousand two, and this occurs about on the one-part of the second verse. What could this logically be? martin
