Ok guys I have a south bend dd. clutch in my 2010 f250. It's the 850/1500 I think it's the 3600. But anyway when ever I let it out in any gear it squeaks so loud that I can't handle it I'm bout to order a different clutch. I've called south bend they said its build up on the disks. They told me to be rougher on it so I started being rougher and still the noise no change all. It drives me crazy. It's only when I engaged clutch that's it no other time. Anyone ever heard this or no what it is? Also clutch is about 8 months old and 4000k miles.
