    I adjusted the clutch, took the aluminum clutch rod off and wrapped it in dynamat. Then put a rubber hose over it and no more clutch noise and vibration through the clutch pedal. :biggrin_255:

    Need to try this solution on my 2014 model 384, our yard just got 5 of them and they all rattle. once the noise goes away by pushing in the pedal just a bit, the ride is nice & quiet.

    I have a '14" 388 , 600 cummins ,18 spd.It's doing the same thing.We think it's the clutch pivot arm under the cab that the two linkage arms hook to.You can reach under the cab and shake the linkage arm and make the sound we are hearing in the cab. The pivot arm is wearing a hole in the side of the bracket that holds it. The truck has 70000 miles on it and no one has come up with an answer to solve the problem!

    U
    u might b over greasing the linkage. Too much grease will attract dirt/sand road grime and then work its way into bushings and bolt and start grinding away at bushings and whatever else it can damage! As the old saying goes "grease is cheap insurance use it often"
    Side note when u first see grease or hear the popping sound u r done!
