All Wheel Drive
Anybody notice any major differences or concerns with 4x4 towing vs All Wheel Drive towing? Considering a Denali with AWD and the 6 liter.
Forum Discussion
Most of these AWD models have a viscus clutch in the transfer case between the front and rear drive shafts, (think fan clutch). This allows some slipage, for turning on pavement for instance, but transfers some power to the other front/rear drivshaft. The more slipage the more transfer. Some of these can be locked--most do not.
