Kit #11690 this part # is for the srw not the true dually.there is also online instructions if you want to see what you need to do to change them out.
on a side note, one advantage to going manaul hubs is that you can use 4wlow without locking the hubs for stump pullin on dry roads.
Thanks Ray
I just had the hubs greased less than a year ago, when I had my brakes done. A Ford tranny specialist said that those hubs are weakest link for my truck and replacing with the Ford part would cost me alot. I'll have to get one of my friends to look under my truck while it's in 4wd and I will almost bet that they will work then. With your comments on the "stump pulling" really puts another vote for manual hubs, like I didn't already feel I needed to go that way anyhow.
