I've been running this truck a few months on 2s Lipos, with only minor repairs and tweaks. So far so good. I've picked up spare gears / dogbones / shock / and cups to try and be prepared for minor things.

After last run, I'm seeing the front wheels spinning like crazy and the rear wheels not doing so much. You can really notice this in the grass, the front wheels spin and the truck doesn't really go anywhere.

Looks like the front wheels are doing all the work essentially. The front and back do not spin independently, and that is still working, but I'm guessing it may be gears in the rear diff ??

I checked the gear mesh and that seems ok. Not really sure what else I could test, any ideas ??

If it is the rear differential, are there any better ones to replace it with ?

Thanks !!!
