yes on the torque tube and yes on half way up is that all the fluid i need? and what do i put in it? I also read a post on cleaning it out with kerosene. Put it on jack stands and run it though the gears then flush out and fill. Any thoughts on that?Thru posts i found out about the vent tube, i have one to put on. I figure the fluid has never been changed so thinking i should clean it before adding new.
