Ok I realized today I shot my whole rear Differential. Everything inside the gear box is busted and I mean everything. I was on Custom RC Cars trying to figure out what items to purchase to get this fixed but I am not sure what a few parts are called. It is hard to find the parts on that site cause not everything has a photo and I am not sure what everyone of the diff parts are called

Also what is the difference between the two of them and which one applies to me, cause I would like all the upgrades

The top pic is the one way diff, the one below looks like the hardened pin. Personally, Id give the one way a miss, after hearing reports on them breaking quickly in off road use.

I still need to know what the part numbers for all the pieces in my rear Differential are.

That should help for stock part numbers at least.

Thanks PJ, I must be an idiot I look at that thing all the time but never scrolled all the way over to see where it showed the diff parts. Uh duh lol

No worries.

Blame it on the beer, or call it a "Senior Moment".
