    :eek1: Okay, my blazer is finally roadworthy and legal. But my mechanic thinks that I might want to think about replacing the transfer case, since it's the orginal 1985 (np208?). Can anyone give me a layman's version of the differences are in transfer cases. I know what it does but I don't know which one is better for off roading.

    Is the only reason for replacing is because its old? or is there actually something wrong with it? I drove mine for 2 years with the original 84 case with no problems and for the past year Ive had a 79 205. neither of which were rebuilt and work fine. unless there was something wrong with your current case I would keep it and if it breaks, then replace it.

    IMHO thats an old way of thinking your 208 should be fine and provides a way better low range than a 205 or 203, its main disadvantage is the slipyoke.

    Np203 full time cast iron case huge weighs alot basically a 2 to 1 low range chain drive

    np 205 super strong cast iron case lighter than a 203 but still somewhat heavy 2 to 1 low range gear drive

    NP208 Aluminum case 2.6 low range lighter than a 205, chain drive and a slip yoke on the tail shaft

    NP241 Aluminum chain drive case I think low range is 2.72 and you can put a slip yoke elimintor on it. IMHO the best t-case of the stock ones for an all around rig thats only midly built.
