Looks like you haved had some teflon seals come apart. They have a wire clip around them and sometimes they break. This helps hold the seal on the guide. You have some of the wire there and peices of the teflon seal. If you look inside the springs you will find some seals missing and probably some other messed up. May not had enough clearance at max lift and the retainer may be hitting the seal causing this problem.
Good luck, Keith Craft
