As for the 3 racing ones, if you are running the normal other gears then it is how you have built the diff. If you screw the blue end plate on unevenly you will distort the plastic gear. It will be build problem NOT product problem
I'm using the 3Racing gear diff as well. And yeah.. you have to get it right or else it will be uneven. tighten the diff slowly, doing the opposite screws at a time.
Once you've built it correctly, you can forget it was even there.
