i have been having some problems with my front diff of my car. It is fine when i go out but over the time i have been out it loosens off so that it does not work. It turns to basically two wheel drive. when you accelerate and then brake there is not respond from the front end just the rear. This keeps happening. The problem first of all way the screw in the side where the accel is held. It loosened and once tightened it worked fine, but this time the screw is still tight and still nothing. What is the problem?
