That explains why I don't break cables or replace housing often, I don't ride the same bike every day.
I also have about the most boneheadedly simple method of lubing the housing and cable without removing the cable. With your bike on the stand, shift into the lowest gear. Pedal so the derailleur aligns with the biggest cog in the rear. shift back to the smallest cog without pedaling. you now have enough slack to pop the housing out of the cable guides and lube the housing and cable, reverse to reinstall.. Do it once a week and your cables and housing will last longer.
