Make sure the mounting points (4 of them on the bike) are positioned correctly. If I remember right, they have a raised horizontal line on the rubber that should be facing up. Sometimes over time they tend to rotate, making it harder to mount and un-mount the Tour Pack and possibly causing the "C" bushings to fail. If the raised horizontal line of the rubber is facing up, you'll find it easier to mount and un-mount the Tour Pack. Might be worth a try.
