RE: front and rear diff oil change questions
Demand drive hub fluid for the front gear case, 0w40 oil of your choice for the motor, rear gearcase is 75-90 gear lube, transmission is polaris transmission fluid (30 wt oil is too thick and will cause failure). Amsoil has a fluid for the transmission. You can susbsitute ATF for your demand drive fluid but it seems to break down too quickly and will start smelling like a burnt electric motor in a very short time. Considering it costs hundreds of dollars to repair the front gearcase then I would highly suggest getting the polaris demand drive fluid.
