I am repairing my dryer and noticed the drum rollers are stiff. However, they seem to fit nice and do not seem damaged or worn. I think the grease seems to be worn/dried. I think if I cleaned them, they would be like new. However, I assume they need some lube. It appears those sold on the site do not have any grease, but it seems as though there should be some, probably a high-temp moly of some kind. Does anyone know what it recommended, and a source?
