This new-to-me Sprite was leaking gear oil out of both rear wheel hubs (the inner rubber seals were rock hard and both had cracks in them.) I installed both rear wheel bearing kits on either side of the Sprite tonight and got to wondering if/why 80/90 gear oil is allowed to hang out in the ball bearings? Why is it not isolated such that the bearings only use wheel bearing grease?
