I was driving home yesterday from the trail and on the highway I noticed my transfer cases were getting quite warm. So warm that I could feel the heat around the shifter area. I do know that my shifters aren't 100% sealed off, but there was a fair amount a heat coming off of the cases. FYI I am running dual cases; TX-10 and a Dana 300. I just rebuilt both cases and all the bearing preloads are set correctly and plenty of fluid is in both of them. Anyone else having the same issue? Or am I concerned over nothing?
