So you mean you put a new pilot bearing in that turned out to be defective? Mine is doing this - new exedy clutch kit installed this past weekend. That, and it seems like I'm getting resistance in the driveline. I can only back up a foot or so before the driveline freezes like dumping an AT into park. I made sure to torque every bolt to spec, all parts were marked to align before disassembly, and the flywheel was resurfaced.
