I just purchased a 1984 Toyota Pickup and I am pretty new to driving a 4wd vehicle. When I first got the truck the 4wd light was not coming on, but the truck was going into 4wd. Now the light has come on and is not going off. Now I am almost 100% positive the truck is out of 4wd, but me being paranoid I feel that it is not. Is there a quick and easy way to make sure the truck is disengaging from 4wd. I have driven the car on the road and gotten it up to around 50-60 and it doesnt really feel like it's in 4wd, but like I said I am paranoid and want to make sure I don't mess anything up. I have heard turning it will make loud creaking noises, but I am not sure if that means going lock right or left with the wheel or just turning to back out of a parking place. Any help is appreciated!!
