I agree with Walt. Rear shocks are not for the home mechanic! Send it back to Fox for a rebuild! Take it back to your LBS and have them handle it for you! They might try to warranty it through Cannondale. Although from what you've described it's probably not covered and they'll charge you for the rebuild! When I sent mine back, it only cost me $50.00, and they put all new seals in it!
