[Question] How setup/select wheels with traction

I like make a vehicle with only the front wheels with traction and the vehicle examples are all 4x4 and in the Blueprints are an bool option to “Affected by Handbrake” but no to turn on/off traction.

Fixed, go to VehicleMovementComponent and in Mechanical Setup go to Differential Setup and change the Differential Type

Yes you can change it but what must one change it to?
