My cables have been on the tower for 12 years now. Last year I pulled
them off and checked the pullys and cables. Cables looked fine but the
top pully was badly worn and needed replacement. I plan to do the
cables this year or next but not because they look like they need it but
just for piece of mind.
The bottom cable is trivial to get off. I lower the tower down and
block off the bottom section which loosens the cable for removal. I
then use a small jack inside the tower to raise the center section high
enough to block it, which then slacken the top cable. Note that the
small auto jack has a long crank that extends outside of the tower so
that my hand, arm, or other body parts are not inside during the raising
process. Common sense will guide you to building the tooling (i.e.,
blocks, etc.) required to do the process.
But I'm with Steve, if your cables are only 3 years old, the only reason
to replace them is if they are damaged, and then, you best find out why
they are damaged after only 3 years of use.
Good Luck
