its not metal (stock anywayz)...thats what exploded and took out one of the screws and alot of gears with it...the one i'm getting for it is metal, so hopefully it will prevent any further problems...but, to answer my own question from what you guys have mentioned, it sounds like i just need to use grease...thanks guys!
