My shop installed an SoS Sport 275 clutch and SoS-provided throwout bearing in November. About a month ago, the bearing started making a constant humming noise when the clutch is fully disengaged, after the car has been driven around a little in gear. There is no noise on startup. The noise ceases when I lift the pedal an inch, starting the clutch engagement, or if I hold the pedal down for about 20 seconds.
SoS and Larry Bastanza suggest that my shop didn't grease the inside of the bearing face where it contacts the input shaft, but that should only make a noise while the bearing is sliding along the shaft, during the pedal movement. My shop insists that they greased the bearing.
Argument for SoS: A new OEM bearing shouldn't usually fail like this.
Argument for my shop: There's not much to go wrong when installing the bearing.
I'm thinking it's a defective bearing, but there's no way to know until they take it out. Any ideas before I drop it off on Monday? Should SoS hold any responsibility to reimburse labor costs if it was indeed a faulty part?
