I have read all the symptoms of the rear axle clicking situation, but mine seems to be different. It only does it one time usually, right when i start up the car and take off, but not on acceleration. I live like 4 houses down from the end of the street, so I usually get about halfway through second gear, and let off the gas and hit the break. Every time I do this, a hear ONE clicking sound and thats it. Decently loud, but not obnoxious. I never notice it any other time; just when i first start off....any ideas??
