No, the geared diff is too big for the gearbox. When the gearbox halves are screwed together it pinches the bearings and creates tight spots. The only way around it is to loosen the gearbox screws until the diff turns free, but be carefull because when you screw it back into the car it can tighten up again as the halves pull together in the blocks.

My guess is that you've warped the plastic as a result of overtightening the screws. These screws only need to be snug, NOT tight (the ones into the alloy motor mount can use a dab of loctite). But once you've warped the plastic you've ruined the parts, and they have to be replaced.
Do as others have suggested and buy new gearbox halves, and assemble and re-install WITHOUT overtightening any of the screws. I'll bet your "problem" will be solved.

I have done this twice now and both have not been over tightened nor have any of the parts warped.
The first gearbox i noticed the lid on the gear diff had been over tightened and the plastic had "butterflied" kind of so i bought a new one, this lid was straight and it still bound, as stated above its pinching the bearings not binding on plastic.
If i put the ball diff in everything runs free.
