3racing ball diff problems

[toysnmore]

Hi all, I have a stock MR-015 with bearings. I just added a 3racing ball diff to the car and my car is very loud now. It sounds like a problem in the gear mesh. But I already checked and made sure I used the correct spacers and pinions for the motor mount. I am just wondering if the 3racing ball diff spur gear is another pitch and I need a specific pinion gear for proper meshing?

Thanks

it's possible the 3 racing came with a smaller spur, change the locators until mesh feels right, I'm sure someone here knows for sure.

Thanks MikeL, I just tried messing around with the meshing and I have solved this problem. In the end I had to use a piece of paper as a spacer for it to mesh properly.

Won't have this issue when you get an aftermarket mount.
