ok well last night the guys and me mad a fire in the woods since it was pretty damn cold..well we had to drive back there and all the puddles were frozen over..well since i drove threw all of it my 4wd light wont come off( but know i am in 2wd) and if i let it sit for a while and go in and drive it only in reverse if you step on the gas it feels like something is stopping it but than you hear a clunk and it moves perfectly..this was happenin to my buddies truck last night to so i dont know it has somehting to do with the ice? or if everything under the truck is just frozen?
