Did you plug off your vaccum line? After installing the manual hubs, and if you had a leak in the auto hub axle seal, you will need to plug the vaccum lines going to the axle. If you do not plug the vaccum line, your air conditioning will default to the defrost vent, when 4 X 4 is engaged.
I read back on the forum after sending this, and I see that the vaccum hub line pulgging was mentioned before....

OK...I skipped from page 1 to page 4 so don't slap me too hard if this was already mentioned....I read through the write up...and one thing that kind of puzzled me.... light coat of grease... I have had issues before with even a light coat of grease, as time goes on, tends to get a little thick and the hubs don't disengage as easily cause the old grease tends to hold them in place. I have always just dipped the hub body completely in tranny fluid then slid them on. I haven't had any issues to date by doing this...am I the only one doing this or am I looking at a long term issue down the road?
BillyBob, Warn even says in there instructions to NOT grease the hubs with anything, they are already coated in something.
Looks like cam break-in lube - very metallic, not much viscosity, but clings to everything.
And not much of it, either.
I did, however, use boat trailer wheel bearing grease, the kind that doesn't mix with water and turn to soup. The blue stuff. Not a lot, just enough around the **** mechanism on the inside of the cover, and over the splines so I could get the thing off again when I wanted to. The splines on the axle, that is.
