replace 99 Tahoe door hinge pins

The lower section of the driver side upper hinge pin fell off. Anybody know how to replace it and put the spring back on the door stop?

Thanks,
Nathan

Come on you Tahoe guys. Does anyone know any tricks to replace the hinge pins on a Tahoe or Suburban, or for all I know, any GM truck or SUV? I need to get the pins replaced on my driver side door. -- Thanks,
