So my exedy OEM clutch/flywheel/slave cylinder was finally installed and i picked it up from the ford dealer this morning. I noticed right away that its definetly grabbin better and has a much better pedal feel, but i have the worst rattle you can possibly imagine. It only happens in gear at low RPMs(not when revving in neutral). E.G. if im going up a hill at around 30 mph in 3rd gear and have to give it more gas, it rattles like crazy, over the sound of my exhaust even. I have no idea what it is. i brought it back to ford and they looked and said they couldnt find anything and they made sure everything was tight that they touched. It is -2 degrees today so they said it could be something to do with the temperature, but this seems too loud. Sounds almost like a really fast heat shield rattle but its not since they checked those. Its hard to figure out cuz i cant get it to do it in neutral, only in gear when im moving! any ideas? i just hope its not something they will have to rip the tranny apart again for because i cant afford that! any suggestions on what to check?!
