lithium cartridge grease

You could try rubbing a candle on the moving parts, the wax is a good lubricant for that sort of thing, or indeed a bar of soap. To go more high-tech, get a silicon spray, often sold as "rubber and nylon lubricant" in car spares places and the like.
WD-40 isn't particularly good for that, it'll help release stuck parts but isn't much good for lubrication afterwards.

try coating the part that slides into or on the bad rail with solid soap [bar soap]
