HUMMING AFTER NEW CLUTCH
I have a 01 Saleen S281 and converted to 373's in 2010. I just had the clutch replaced at a very well known shop in Metro Detroit. I have never heard humming from the rear like this before period. From 55-90 mph there is a definite humm, and at 80mph it is the loudest.
I drove up to 80mph on the freeway and put the car in neutral and shut down. Noise persists.
Is it possible to be the drive shaft?
