I was just remembering that when I had my knuckle replaced, the mechanic who replaced it took the axle out and it was full of dirt he didn't even clean it at all when he put it back in I asked him if he was gonna clean all the dirt off, and he told me that the dirt wont hurt anything inside like the gears or anything else, my question is was he right? I now started to hear a little noise I dont know where the noise is coming from it sounds like a grinding noise would it be inside the pumpkin? shoot I hope not I guess my question is would dirt hurt my gears or anything inside my pumpkin if anybody knows about this please help me Thanks. keep blazin !!!
