For context: Rustler VXL 4x4

So I changed the spur gear and now this is what’s it’s doing. The drive shaft isn’t turning the wheels but the spur + pinion gear are rotating fine. I had to remove the back of the car to do this. And I’m super confused to why it isn’t working.

Also, another issue I found out is that I broke my tiny cheap tool inside the grub screw of the pinion gear. I’ve got a 3s battery and was hoping to change my pinion gear to a 18t but now it’s stuck on 11t forever…? 🥲
