Ive ran close to a gallon through my Kyosho STR since ive had it and i was just lookin it over tightening everything up cleaning it etc and i open up the front end and i see that my drivegear is all chewed up as well as the gear on the front differential. I opened up the rear and it is fine. Where did i go wrong? Why would my front gear be all chewed up and not the rear, is it shims? This is my first time building a truggy, could this happen from not having enough shims between the diff and the diff case? Ive ordered new gears but before i reinstall them and chew em up again id like to know if anyone has any ideas as to why this happened and how i can prevent it in the future.

Heres a pick of what it looks like.
