Alright, so i experienced this for the first time a week ago. I was going up a ramp ( that kind that goes in circles) and i started hearing this horrible clunkcing noise in my dif. my left tire was skidding. So i stopped and put in 4 wheel. It did the same thing. when i finally got on a straight away, it stopped. Does this mean i got a bad dif. ( i'm going to school for mechanics so i understand how it works) i've never really experienced this before. I've heard th g80 is a good dif, but would it be beneificial to swap out my stock dif.
