chatter under 5 mph when truck first gets going. Manual transmission

[dieselbop]

hey everyone,
I have had a noise/chatter ever since I got the truck and it is getting real anoying and embarassing. I have a 99 superduty psd. It has a manual transmission. When the truck first gets going I hear a loud chatter noise almost as if the rpm's are to low. I don't know if this is normal? It is pretty loud and it makes the truck sound like P.O.S. Any knowledge would be appreciated!!

Is it while slipping the clutch to take off?

Say i had a 97 F150 with a 5spd and it did the same thing especially when it was cold and it was the throw out bearing. They rattle really loud.

Mine does that too early 99 but im getting a whole new clutch setup

yes, it is when slipping the clutch while taking off.

Well, it could be like Dan said and be a simple throw out bearing. The part is fairly inexpensive. But, you will have to pull the tranny to change anything. With the age of your truck and the mileage most likely on it, it makes me think you'd be best off replacing all the clutch components for a couple hundred more. And not having to deal with it ever again. Almost every time I've had those symptoms, it was usually caused by my stupid self going through deep water with a warm/hot clutch. Not only does it mess up the throw out bearing after time, it also puts hard spots on the pressure plate. I'm sure some would disagree with me but, I hate pulling transmissions since I don't have a lift. So I have the mentality of doing it once and taking care of it all at the same time.
