Hi!

Is somebody noticed a molding problem with front & rear differential crown gears?
I have some metal protrusions, an excess of molded metal between differential bevel Gear's teeth and in the four holes :( I had to remove some metal to put the four screws.
I'm surprised because the 2018 features says : "Improved construction and production details on both front & rear differential crown gears results in quieter operation and increased reliability"
I've never seen this on my previous XB4.
After four five minutes run, I can see some damages on the drive gears. (I use graphite Hudy grase on it)

Any idea?

Thanks
