how to reattach the hinge joint after it is destroyed?

I have bike game setup in which when a player crashes the joints are detached and player becomes ragdoll but on retry the player should spawn at a checkpoint now I want to use the same player and placed it on the checkpoint everything works fine but I am not able to reattach hinge joints as they are destroyed and I don't want to use player prefab as there are lot of references in the scene.
