XV-01 Eating Diff Gears?

[Dman07]

Has anyone else had issues with their XV chewing up differential gears? I'm having issues with the back of the output gear (GV2) getting chewed up by the pin it sits on to drive the output cup (BA20). My front differential chewed the gear up so bad, it almost looked like the back of the gear was designed that way! And now it's acting like that's happening again.

Any ideas on how I prevent this? I stuffed a metal gear diff kit in the front as a precaution.

I've outfitted my XV-01 with a pretty standard Castle Sidewinder SCT and 3800 kv motor combo. I'm running a 5800 mah 20c lipo and a spare set of wheels with HPI's Pirelli rally tires. Otherwise the car is stock.

That's the 4 pole motor yeah?

I'm only running the Trackstar 10.5T motor but the only drive line issue I've had is wearing out the Tamiya pinion.
My diffs still look new, along with the pulleys and the idler gears.

Do you have the washer under the cross pin on your output shafts?
If not, that may bring in excess play/movement.

With my experience with the kit so far, I don't believe it needs the steel gears.
Saying that though, mine is on asphalt 80% of the time.
Off road and such, while a forgiving surface, it's still really hard on the car with shock loading and such.
