Hey guys. Just like many of you, I hardly use the 4W on my 02 Sportage and after yesterday's 24" of snow I found out today that my 4W-drive is out. I have no clue how long it's been out but it's been some time I'd wager.

I'm thinking of getting the autolocking hubs from Warn to replace the stock ones. Couple of questions first though?

I get how manual locking works, but how does automatic work without the vac-hoses? Does the diff start turning the axles and the hubs just lock in step, or is it something else that I'm missing here?

Is there a warranty on the parts themselves or do I have to buy from Warn to get the warranty? I don't want these blowing up on me and forking out money for another set. I want them replaced if at all possible.

Yes, I'm boring. I'm looking to change that.
