So about 3 Months ago i replaced the clutch, throwout bearing, new steel bearing retainer, and pilot bearing. Install went great and everything worked fine. but about 3-4 weeks ago, all of a sudden depressing the clutch pedal feels rough and feels like its grinding. As i drive the car for about 10 miles, it stays rough but then starts popping right before it engages. It will do this untill i turn the car off and let it sit for about 4 hours and it does the same thing..i would apreciate any suggestions as to what this might be.. Thanks...
