We had both cables replaced ('88 YS pedistal), last winter. One upexpected problem that had been contributing to our stiff actuation was that the SS rods had reacted with the cast aluminum casing that they went thru to the inside of the pedistal. We also increased the radius of all the cable run under the cockpit. That part of the pedistal was sent out for new powder coating.
What with the passage of about 20 years, it was time for new cables anyway... but these other aspects of that system should be addressed at the same time, IMO.
Best,
