Re: Lubricating cables
If your cables are out of the housings, the wheel bearing grease method is probably the most ideal.
Dip the end of the cable in the grease tub, insert it in the housing, and use the buildup to coat the rest of the cable. Add more grease as needed.
Coat all sides of the cable lightly before it goes in the housing. Cable actuation should be silky smooth and stay that way for at least a year.
Don't use WD-40, that stuff is useless for lubing cables, from my experience. It will make cable actuation "gritty" after awhile, making reapplication necessary.
Don't get me wrong, it will "work" but it is far from ideal as a long-term lubricant.
