    Got a 90 Jimmy(FS) with 350, NP241c, 700r4. Can I straight swap the 700/241 for a TH400/205? And does the 205 bolt right up to the 400?

    if you get the 205 with the 400 out of a burb. - or you will need an adapter to make the 205 fit the 400- it was not extemely common to see the two together . call 337-527-1044 if you need the adapter -glen may be able to help- or e mail me i might be able to locate it - forwhlr@saber.net

    Thanks. So what is the most common setup for the part-time mudder/trail-runner? (without really having to worry about breakage?)

    the 400 205 combo is what i'd use for a no worry 4x4'in fun mudding day- over and over- especailly with any tire more than a 35 - plus you need to get rid of the ifs up front if you have that- call oru- they have a cool kit -jesse

    Speaking of IFS. Don't have one. But I do have auto lockers w/fulltime NP241. Can I still just swap them out for WARN manuals???

    I know that you know, but let me remind you that Blazer, Jimmy and Suburban didn't go IFS until 92

    Sorry if I misunderstood your post, but you have auto hubs with the NP241 which is a part-time transfer case?

    I've got a NP241 and autolockers (id unknown), and I was told the NP241 was fulltime. So I was wondering if I could put manuals on on a fulltime transfer.

    Unless I am very wrong, the NP241 is a part-time transfer case. I also have a '90 Jimmy with a NP241 & 700r4 and manual Warn hubs. I am quite confident it is p/t 4X4.

    Shwoooooooo. That makes me feel better. You'll have to understand, I've grown up around auto-mechanics all my life, but this is my first 4x4, so I sorta feel stupid. Which I probably am, but thats another forum!! LOL
    Thanks Derf. P.S. Are they really that easy to put in? (WARNS, manuals)

    There aren't any stupid questions. There is such a wide variety of set-ups on these vehicles, almost anything is possible, so never say, never. It is my expierence that hubs are relatively easy to install.

    The only transfer case that I know is full-time is the NP203. If yours were a full-time transfer case, you wouldn't need auto or manual hubs, just a fixed, locked, hub (as in my Blazer). Check out my site for pics of my "locked" hub.
