The trouble with 3racing diff is the thrustbearing, mine did not even last a battery. I even took the diff apart and regreased it before use. Changed it to Tamiya TRF415 thrustbearing and holds up well. Bought a new diff and tested it with carbide diff balls and Tamiya thrustbearing, It's one of the smoothest diffs i have ever felt. Runs great and excellent traction. The diff is good, but not right out of the box!
