Repalcing tires, Pirelli Scorpion for Anakees. Manual mentions not to remove grease from axle? Is there a reccomended grease for axle? Can one use wheel bearing grease to coat axle with. The front did seem quite grayish? Or is it best to do as they say just not remove grease from axle? I read most of this thread did not see mention. Tire threads too long to reread. That Pirelli really did not want to leave that rear wheel.
