howdy all, and thanks for your input. i have an 05 sonata, 2.4l with the 5 speed, with just over 100k miles. The car runs great and all but there is an issue with the clutch. When sitting in neutral there is a loud 'knock' coming from under the hood. When the clutch is pressed to the floor, the sound stops. i mean knock like a woodpecker kinda knock. Sometimes when i get in to go somewhere, push the clutch, turn the key, try to pull the stick outta first to reverse and it wont come outta first. i have to turn the car off, pull it out of gear then start it back up again. Thats pretty intermitent, but the knocking sound is getting worse and i'm thinking there's something loose. oooor there's a familly of feathered tree pokers in there. Any ideas where to start? Thanks again.
