For the past few months I have had this noise, which has become worse, which sounds like a loud "bang" comming from underneath when I accelerate from stop at a normal speed. When I take off slow, it doesn't make the noise. When I accelerate like normal it "bangs" like
3 to 5 times. When I accelerate fast, it bangs only once. The engine does not hesitate or jump or anything when it makes the noise. I heard that it could be my gear box for my AWD. Does any one else have this problem? How much is a gear box and can I change it myself with any Trans. tools. I need it to last me another year or so. Help.
