@ko I'm sorry but I don't know what's happening in testing I hooked it up to wheels and it was working. I would say to NOT power the bearings in to blueprint but to add a bearing + gear on the creation to power to drive gear(green). I also haven't tried it with suspension, but that and making sure to power the gear with another gear are the only things I thank I might be doing differently. In case this doesn't help I'll add a example car.

can't get this to work, have it hooked up and it just spins without powering the wheels. idk what im doing wrong.
