i test drove a car i wanted to buy today. the owner told me that the clutch is rather new but that the new throwout bearing that it came with was pretty crappy and therefore was making some weird noises. i drove the car and it would grind gears sometimes, and sometimes you wouldnt hear a thing. when the clutch is disengaged and the car is rollling it makes a whining noise. if i put the car into first and then into neutral then 2nd instead of straight to 2nd the car wouldnt grind. is this a problem with the throwout bearing or something else? TIA
