I get a metalic clicking noise when I back up or drive forward. Hear it more when I step on it. Just started yesterday. With the car in neutral I can move the prop shaft by hand right or left about a half inch and it kinda makes the noise. I can see a bearing on the diff end of the shaft & a u-joint on the tranny end of the shaft. Would it be the bearing or u-joint? I can't find either on ECS or Blau. Help. Thanks.

 

Just remembered when I had the roll over recall done they said I had a leaking prop shaft seal. I don't see any thing leaking. Is the prop shaft seal on the front end or rear?
