I have a 1994 4 runner and I'm having a problem with something sticking or locking in extreme cold weather. when i go to take off the truck won't move and then will just pop and take off. I thought it was my brakes and thought it might be the 4 wheel drive. My mechanic is having a hard time locating the problem. He does not specialize on 4 runners. one time I was on a slippery surface and the truck wouldn't move but the back tires just kept on spinning. Was wondering if anyone has ever had this problem.
