The red gears work good, and so do the blue gears. Make sure the gear on the axle is the same color as the gear that sits on the little metal poll. If those don't match up you can have bad meshing and that can cause the loud noise. You said you are going to use the blue axle gears. Use the blue "free" gear also (not the gear on the motor, but the gear that transfers the power from the motor to the wheels) Hope that helps you out.
