Need some help here I have an 05 AWD 1500 today was the first significant snow so i ran to the gas station for son fuel and it dose not feel like the front end is working i tried it in 4HI and it still feels no different even when you turn lock to lock you don't get that chatter of the front end wanting to straighten out there are no odd noises or sounds the light for the 4HI and 4Lo comes on like it should but it feels like it is defiantly not working. Any insite on what to look for or check would be very helpful
