I have an annoying grinding/scraping noise coming from what sounds like my diff. I just installed it yesterday. It never made this noise with my old one. Its just a basic welded diff. It only makes the noise while i'm on the gas or when slowing down. If i take it out of gear or push inthe clutch it stops. I don't believe it's ever been apart, just welded and the cover put back on. I'm thinking it might just be worn or high mileage, but the sound is kind of annoying. I put 1.5 quarts of fluid in, till it came out of the fill hole. I don't know what else it could be other than it just being worn.... Anything else to check?
