Hi, I just bought my parents old Subaru Outback 2000 4cyl manual. Having never driven manual before I was very hard on the clutch and stalled multiple times. Dad drove the car back home and we noticed a vibrating noise coming from the front of the car when decelerating(sounded like it was coming from near the gearstick). The noise seems to stop when the clutch is pressed in. Any ideas what might be causing this?
