you cant lube the cable it's self, it is a sealed unit. There are lube points on your helm (under you dash) and on the rudder. They both have zerk fittings so you have to use a grease gun, with marine purpose lubricant. I do them once a year in the spring when im dewinterizing. If your steering is tight it may also be time to replace the cable, they seem to wear out every 5yrs or around 500hrs.
