Sorry to hear that, the transfer case is not a cheap fix, although it's cheaper to repair then replace, it all comes down to your comfort level in terms of your abilities. I'm sure you can source one in serviceable condition for a reasonable price on-line or maybe even locally. What did your driveline specialty shop say about a replacement or rebuild? It is a Borg Warner and replacement parts are readily available but I can't say offhand what the model number is. If you crack it open and diagnose what needs replacing, your friendly neighborhood CarQuest can supply you with the needed parts. They seem to be a better choice then Napa, at least around these parts when it comes to foreign car parts...
