2003 GT, 5 speed with 23,000 miles. Over the last couple of days I have felt a slight vibration or knocking under the floor board at the pedals. I thought my H pipe might need to be tightened so I crawled under the car and checked it out. Everything was ok so I started looking around for any suspension stuff and all of that looked ok also. When I got home this morning and pulled into the garage I noticed a grinding noise, but when I pushed the clutch in it went away. If I release the clutch the noise comes back and you hear a slight click. Could the clutch being going bad already with only 23,000 miles? I don't drive it that hard, but I am afraid the previous owner may have. Any help would be great.
