i did some online searching and came up with various different answers. 01 1500hd. the driver side seal is leaking, passenger side is seeping but can hold off on being replaced. i see the cv axle bolts to the hub on the diff. if i unbolt that, will the hub simply pop off or does it have a nut on it? im assuming its held in the diff with just a ring. excellant mechanical skills, just dont work on small stuff like this very often
