Flex dic seems good. no visible cracks or separation. Is there something specific to look for to know if it is faulty? I also noticed today that my driveshaft has thick green and orange lines running across it that looks like spray paint. Does this mean it has been removed and marked for some reason, or do they come from the factory with these markings on them? I'm the third owner of the car, and I have few service records on it.

thanks for your time.
