I have replaced clutches and trannys. No problems there, but my question is, what might be the noise coming from the clutch? It happens when I get on the fuel a little bit. It's sort of a chatter. Not to bad, but it drives me nuts. No slipage or anything. The noise will travel up threw the pedal from leaning on the bracket on the firewall. If I press in the pedal a little of the noise goes away, but I can still hear it and feel it a bit. It almost feels like at an idle in neutral the clutch is engaged a little. Good clutch with worn pilot bearing? I will replace clutch soon just because the noise is making me crazy. I don't want to though if there is a cure.
The pilot bearing is not turning when clutch is fully engaged.
Check inside on the bottom of the bell housing for pieces of broken springs. |

As for chunks, I was in there for my last adjustment, and everything was clean. It's been doing it for about 7 months. Never gets worse, never gets better. If it is my pilot bearing, I will just change clutch while I'm in there. Tranny has to come out anyway.
Thanks for the suggestion on the spring. |

sidman82, I have the same "noise" problem you have. Adj. is good, no slippage, but a "rattleing" noise that comes up through the clutch pedal, push the pedal down a tad and the noise quits. Does it mostly when the truck is not pulling or decelerating (neutral load). '03 Pete 600k.
What'd you figure out? |

| I'm inclined to agree with Bob on this one. Loose or broken springs causing some "beating" in the clutch center hubs. Or possibly just some loose/worn linkage. |

| Talked to some knowledgeable friends and as soon as I get back home I'm going in for a clutch. Maybe overkill, but in my past experience, noise is an indicator of problems. I'll update later. |

Thought I'd update you guys on my last post about the noise coming up through the clutch pedal.
Had a brand new clutch installed last week and the noise disappeared :D . My mech. couldn't swear it was the release bearing, as nothing in the old stuff was broken or worn out. I'm just glad the noise is GONE! |
