It's been decades since I've had a four wheel drive that did this, and I used to know the cause. But maybe someone could refresh my memory a bit. After pulling forward and parked, I have a very slight toe out on my passenger front. When I back up a length of distance it really toes out, I'm thinking the tires would be about equally toed out, but the passenger side as I stated has a slight out before reverse. Any help would be appreciated. Thanks
