We just got our first good amount of snow up here and my 4 wheel drive is acting up. When im in the snow in 4 wheel drive if i force the truck at all (ie spin the tires) once in a while the truck will pop out of 4 and grind back in after i stop the back tires spinning. Anyone know what the problem could be or where i should start looking? 4 low is fine it only pops out of 4 high. Thanks.
