I think my 99 Legacy 5-speed has a slipping differential--front, center, or rear. How can I diagnose where the slipping is happening? When my Legacy is going up a hill, and I give it more throttle, the speedometer reading increases (it's a Brighton so no tach) and the engine get louder, but the speed doesn't seem to change. So I think I can rule out the clutch as causing the slipping. Also, if I can't get up a hill in first gear, I can shift up to second gear and it will go up the hill better...but with some noisy complaining. It was an intermittent problem--going months between slipping, but recently it seems to have become chronic.
