I recently had my clutch replaced on my 2001 Dakota 3.9L. I used a duralast clutch kit (I know poor choice) and had my friend, who is a mechanic, replace it.
After a week of driving I began to hear a noise that sounds like a chirping that increases as my RPMs increase. On cold days it is far louder than it is on warm days, and it is not audible after the engine has warmed up. (On cold days the sound remains regardless if truck is at running temp) He replaced the throw out bearing again to see if that did the trick, though it did not.
I have been told it could be a just a noisy gearbox, (though this sound is new after the clutch was replaced) bad pilot bearing (though that was just replaced) or possibly a input shaft wobble...just trying to see if anyone else may have had a similar problem. Thanks for the help.
