Been noticing a grinding type noise when idling. It goes away when in gear and just pressing the clutch in. Any ideas?
Sounds like a clutch release bearing problem. Pull the inspection cover and take look for metal shavings in the bell. It could be a few things. Is it a DD engine? I know they had an issue with the starters getting stuck engaged, which makes a grinding rattling noise, but that would not come and go with the clutch pedal.
a clutch bearing will do that, dont know if they still have a grease zerk for them on the newer trucks
