I'm Neal and I am here to assist you. Only accept when you are happy with my assistance. If I can't help I will open your Question to other experts.
I practically never see any questions on here about the transfer case or differentials on those. They seem to be very reliable with a much lower than average failure rate. I would not be worried about that at all unless there is some reason to be concerned like odd noises and such.
Thank you for your response. Is this a good vehicule for traveling long distances?
What other major maintenance can I expect to see?
What about the A/C and the rear end differential, are there any problems? How much would these repairs go for?
I almost never hear anything about the rear differential, and the best solution for a bad one is a good used unit with parts and labor less tha $800, and the a/c seems to be a non-issue but if a compressor needs to be replaced the bill is also going to be around $800 for compressor, drier, refigerant and labor.
