Especially during cold weather.. there is a sound coming from the back during higher rpm's 2500+. It sounds like a belt is slipping or crickets chirping (only way I know to describe it). Doesn't happen all the time but damn is it annoying hearing that. Happens at all speeds and doesn't matter what gear or whether the clutch is pressed or not.

It sounds almost like a throwout bearing... but that would sound more like it was coming from your foot area, not the back... and it would go away when you pressed in the clutch.

Try greasing your driveshaft.

Definately not coming from under my foot. It sounds like it's coming from under my bed.. I can hear it a lot more if I open the rear window so I know it's coming from the rear..

Forgive my lack of knowledge.. any particular type of grease to get and where exactly are the points that I grease? Does it have the same type of connections like a 4 wheeler or snowmobile have on the suspension parts? You put the tube/hose on the connection and pump grease into the fitting?

Take a look at the carrier bearing. I had two replaced under warranty due to chirping. They only made noise during cold weather, the sound didnt get faster or slower with speed, would only quit when the truck was at a stop. The bearing in there now does the same thing. I'm gonna live with it this time.

I don't believe mine is speed related.. it's more RPM related.. The noise doesn't get faster or slower like yours though.. just either a constant chirping/squealing or it doesn't do it. Like I said, below 2500 rpm it won't do it.. almost like the vibration from the engine whatever is back there to squeal..
