my tahoe is awd being that it is my front diff is always engaged and does not have the actuator on the front to disengage it. being so if i were to, say put in a autotrack t-case would it be ok as long as i didn't use the autotrack part or does the front diff have to disengage to use 2wd? i'm considering doing this just because it robs power and gas for every day driving. or would a SSS t-case be better? what kind of milage do those guys get? better than 14 highway stock?

 

i really dont know how the awd system works..all i know is that my front driveshaft is always spinning even if i have it in 2wd....its just not engaged with the front diff somehow... oh yea i have push button 4x4

 

yeah the early models did that then the newer one like 04 or something it changed. i could have swore.
