Try a reputable transmission shop for a 2nd opinion. I am ignorant when it comes to 4wd but thought the transfer case only affected the front wheels and you say rear wheel power loss. What happens in 4 hi and 4 low? BTW my buddy just got a new case done for $800 so I would shop if you have a little time and that's the part you need.
