    I think I have auto hubs. Is there any reason why I can't use these hubs? I can simply wait for them to die, and then get new ones, right? Then - when I do need new ones, which are better... locked or manual??? I wouldn't really mind FT 4x4... but is this hard on the drivetrain???

    You can't run locked hubs on the street with the NP205. 203 is the only one that can do that, since it has its own way of "slipping" when in "all wheel drive" mode, which no other common (for our trucks) case has the ability to do.

    I'd run the autos until they decide to quit working properly, but they WILL decide to quit at the most inoppurtune time, case in point: In a creek, trying to get up the muddy bank to the road.

    I think most would agree that between auto and manual hubs, there is no choice. Manual.

    BTW, I never beat on my truck, and had just cleaned the auto hubs when they decided they didn't need to lock in. Great feeling when the engines spinning 2000RPM and they lock in. Ouch.

    I have never use auto style but have heard that people hate them cuz you are taking for granite that the 'auto' part acually locked your wheel to the axel. I would swap um out for Warn Premiums. Not sure what you ment about manual vs. locked??
    If you run in 4x4 all the time your gas millage will suffer and you will put unnessisary were and tear on your front axel.....

    If it is a offroad only truck, either the fulltime hubs(sometimes called "Slugs") or manauls would work. IF it is street driven, definately go with the manuals.

    Never use Auto hubs, they are junk.

    Well, they wrok good for a while, then that one time when you really need them, they dont. It happened to me....

    I wouldn't rush out as soon as you get this, but I would get some in the near future...

    Better to be safe than sorry..

    So can you put the warn prems on in 30 mins or so? They look good I think. Where can I good some at a good price. I suppose not 4WWP. Too many people don't like them. What other places?

    Most Warn Prem can be gotten at the local parts store for about $75... I grabbed the Mile Marker Stainless Steel Supremes for like $60 from Summit.. They work and look great!
