<p class="MsoNormal"><span style="font-family:"Arial","sans-serif"">Approximately 15,000 miles after having replaced the carbon release bearing, I noted a similar sound – actually within a little time it turned into more of a grinding sound. Upon inspection,
the release bearing was completely worn out. I blamed it on a poor quality release bearing. While replacing the bearing, I noted that the slave cylinder (without depressing the clutch peddle) was pushing the bearing into contact with the clutch plate. Thus
the bearing would be continuously in contact during all driving conditions (mostly70 MPH on I75). I bled the system several times – no help. I changed the master cylinder – no help. Something was pushing the slave cylinder piston out. I didn’t think there
was a spring in the slave cylinder – there wouldn’t need to be one there anyway. Then I took a
<u>very close look</u> at the Moss slave cylinder diagram. There it was, just barely visible, peeking out of the cylinder – THE SPRING.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial","sans-serif""><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial","sans-serif"">I removed the spring. Now 25,000 miles later everything is still working fine!<o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:#3333FF">Thanks for the input and you may be correct, but as said it is possible that the noise is nothing new and simply a function of my driving the car buttoned up. hearing what was not evident earlier. <o:p></o:p></span></p>

<p class="MsoNormal" style="background:white"><span style="color:black">You know, by now you should have figured out you have to take it apart in any case. There is nothing you can do while it is assembled in the car. 99% of the time you never know what is
really wrong until you disassemble and inspect. Best case you will end up with a new clutch and throw out bearing. Hopefully nothing wrong with the transmission, but it would not hurt to do a cursory internal inspection while it is out. Better to head off
trouble before it becomes a real and expensive problem. Or, you can just drive it until it breaks. Just my 2 cents.<o:p></o:p></span></p>
