It is a quick fix. The cables are adjustable at the quadrant connection, all you need is a couple of wrenches. I just got the boat back after dropping the rudder and the yard had too much tension on the cables, steering was stiff. I loosened by about 3/4 inch.
Steering cable adjustment may be necessary from time to time, and the goal is easy steering without "too much" play. The theoretical deflection of the cables is 1" per foot, or so I've always been told. Loose is better than tight, which wears out the sheave bearings.
If you suspect the drift/roll pin issue Baslin mentions, that means disassembly of the pedestal (unlikely , I hope). See Photo #12
