A couple of months ago, there was a thread started by DodgeBlue...
I think I'm now experiencing the same issue. Essentially, I can't detect ANY difference between the 4WD/AUTO setting and 4WD/LOCK(High) on my drive selector.
I KNOW that I'm getting help from the fronts, but regardless of how sharp I turn on pavement that's just a bit wet, I can't detect ANY of the normal axle load-up I think I should feel in 4Hi. No slip/hop/chatter/anything, just a smooth turn as though I was still in 2WD.
Last night I had my first plowing experience in this truck, and while it did a good job, it sure seemed as though I was often spinning the rear BEFORE getting ANY help from the front.
It's as if the fluid transfer component of the transfer case isn't locking up, and I'm really staying in the Auto mode, even though the selector is in 4WD/LOCK and the light on the dash is supposedly confirming that.
In the last thread, it seemed like everyone with definitive experience AND a transfer case with the Auto capability had a 2010. The only 2011 owners that had any direct experience to share seemed more similar to what I'm getting now.
According to the owner's manual, when the selector is in 4WD/LOCK, the front and rear driveshafts are locked together, and to me that means if a wheel is spinning in the back, at least one HAS TO BE SPINNING in the front.
Now that there's more snow around, can any 2011 owners confirm that theirs DOES feel like its supposed to in 4WD/LOCK? I don't want to go back to the dealer and get the "that's normal" answer.
