I was running my Slash 4x4 with a friend, and I was running it pretty hard when it started grinding and was loud. The grinding was a result of the gear mesh getting screwed up because the motor mount screw was not tight, and that is solved, but now the car is just out-right loud. I checked the mesh and slipper clutch and both are fine, however I am stumped as to what it could be. If anyone has any ideas or suggestions they would like to share, it would be great. Thanks for helping out!
