Default Centre diff binding/squealing.. Help!

So I took my 06 sti into a Subaru dealer because the diff has been squealing and binding lately. I will post a video of it soon. But the dealership said they heard metal shards clinking in the transmission casing. Which would mean the centre diff is gone/missing teeth. So my question is what caused this? And how do I go about fixing it? I am taking the car to a shop called vex tuning in calgary where I live. They will give me more info. I just thought I would ask you guys your opinions on this. I think it's something that typically shouldn't happen to these cars. It has 74000 miles on it (118000 ish kms). Anybody??

Thanks for the help everybody (just kidding). For those of you who may be having the same problem, the oil in my transmission was incorrect, even though the Subaru dealer chose it and put it in. There were metal shavings or teeth floating around in my transmission/diff casing. It was just binding because of the incorrect oil. Needless to say I will not be going back to centuar Subaru (Calgary) EVER again.

Sometimes you just get a dead thread haha! I'm not actually sure of the type of oil. It was changed by the Subaru dealer but it was not correct for the car. It was quite an aggressive noise coming from the centre diff. I figured the oil was out of the question so I had vex performance in Calgary check it out for a more serious problem. They diagnosed and fixed it quickly. I would be interested to find out what oil they put in though. I will give them a call tonight to find out!

How would they know the wrong oil was put in? So a flush and fill cured it? Metal chunks be damned?

I haven't been able to get the oil info. They drained the oil and filled it with the new supposedly correct oil. The old oil is being tested they are just taking their time. The way it sounds to me is that I DID in fact have metal in there and the flush and fill DID fix it. I will post more info when I get ahold of vex again.
