I just drove home from school in worcester (A 50 mile drive) and I kept hearing this whine coming from the rear of the car. Only appearing when i press on the accelerator. The differential seemed to be the most likely problem. What do you recommend I do with it? I know it seemed to be leaking fluid before, so can you guys recommend me something I can do to make it better/should I give up on this one and buy a new one, what should I do???

This is the first time ever the noise was ever heard.
