Contour Enthusiasts Group Archives Forums General Troubleshooting Chattering sound At low RPM in each gear

My Contour is an ATX, but I've had many cars with MTX. In every one of them the sound you are describing was the throwout bearing. I'm not sure about the Contour MTX, but most MTX have a throwout bearing. The clutch actuates a fork which pushes on the throwout bearing which in turn pushes on the fingers of the pressure plate to disengage the engine from the clutch disc. The noise is because the throwout bearing's lubrication is drying out and the rollers aren't getting sufficient lubrication so they make noise. Maybe I'm wrong here, but just trying to put in my 2 cents worth to try and help since it's a very common problem with all MTX cars I've ever owned.
