Servicing Automatic Hubs

[threejacks]

I have read all the post on Automatic vs. Manual. So I know all the comments on switching. This is not what I want to know. What I want to know is what is the reccomended procedure for servicing the Automatic hubs. Seems like I have heard something about ATF to lubricate but have not been able to find anything on the forums. I drive a 2 wheel drive, this is for my son's truck. It is a 2000 F350 Dually 4X4 with the Automatic/Lock hubs.

I took one of mine apart because I heard a noise when spinning the wheel. They are not very complicated and a lubricated with grease. That was what was in there so that is what I used.

I'm beginning to see why everybody cusses Automatic Hubs. Does anyone else have a service procedure?
