I took it one a drive yesterday and one the way home it developed a LOUD rattle, sounds like a cheap mustang I once drove. I guess I need to send the unit to Mark Basch for new bearings or something, not really sure what it is though. Definitely sounds/feels like it's coming from the center of the SC driveshaft.

unlemming said:Is this a DIY type thing? (relatively, I've tackled headers and fuel pump but the SC was a bit much for me). I've read a lot of posts about this mythical spider but I don't really know what it is..hopefully it's a easy fix
*edit: Additional details, it's worst at idle. If I let off the gas and depress the clutch pedal it is quiet until it reachs idle engine speed. Under load, it's not as loud as idle but it's still pretty bad...as the RPMs climb it gets drowned out with the sweet sweet music of the car; SoS headers and Taitec GTLW exhaust, btw.
unlemming said:Interesting, is there a specific torque setting to aim for or just as tight as I can reasonably get it?
I'm going to attach a .wav of the noise it's making also. Friggin loud, you can almost hear the engine
*edit Erhm, I'll link it since it doesn't like a .wav attachment:
