So I'm at a bit of a conundrum. I don't know a ton about AWD. I talked to the guy at RS Gear, and he says I should drop the NP149 t-case and go with a BW 4473 (because I'm thinking hard about the T56 he has with the t-case). But, I've read a lot on the 4473 and how they've failed a lot due to poor lubrication. I haven't found as much about the NP149 being problematic, and I know they come in the Silverado SS's, Escalades, Denali's, etc.

Anyone have experience/valid opinions on this?
