i have a 2001 3500 dually 6 speed 2wheel drive. It seems that when i start off from a stand still i hear a sort of grinding noise only at about 800 rpm and then once it passes that point it is gone. any ideas thanks for the help

 

How many miles on the clutch? May be the rivets on the cltch disc scrapping the pressure plate or flywheel.

 

I have adsolutly no idea. Is it pretty hard/expensive to replace the clutch and flywheel

 

I'm thinking it may be a worn/dry pilot bearing. They typically growl when you slip the clutch to start out from a stop.

 

My 01 2500 6-speed has done it in 2nd gear (off and on) since around 80K. Dealer had no idea what it was, checked the tranny and the clutch. At 128K and it still does it, no better but no worse either. Only does it in 2nd never 1st.
