Here's my situation. I have a 97 subaru outback limited 2.5L and just put 4 new tires all around. Right after I installed the tires, I lift up the car so we can spin the wheels to hear if there are any bearings bad. The moment I hit the gas(I guess I pushed it too hard), grinding noise came on from the rear. The noise was just like the one in that post. I thought it was the LSD-limited slip dif. but I checked and subaru did not put any LSDs until 2000 and up(at least not on the regular non turbo vehicles). While still on the lift, I got closer to the place where the noise was coming from and heard that the noise is coming from the front of the differential. Diagnose: broken piece inside the differential. I just got another diffy for 150$ and everything's fine. Cheers Jeff
