Do you guys put oil in the diffs? If not look at 5k silicone diff oil from any rc website

I soaked my with silicone. But many don’t, and drive without problems

In ALL model car diffs the cup should be filled with silicone oil. HigherViscosity makes the diff stiffer but those little gears will move so fast that they will wear easily
