It seems to need to be rolling to get the awd automatic button to tell all the wheels to rotate. So if you are on Ice and stopped try using
4Hi or 4 Lo
I had to replace one of the sealed front bearings a long time ago. I now have 115K miles on this truck and it seems to be as strong as
the day I drove it off the showroom floor.
