That's always a hard one! When one can't really get at the bits that need greasing, I use a spray-can "Chain lube" available in many places. It has a fairly narrow spray pattern, will send the lube at least half a meter, and makes a hell of a mess! It is a normal sort of grease dissolved in a volatile carrier. When you spray it on something, it will penetrate into crevices to a fair degree, then the carrier evaporates, leaving the grease fraction behind. Works pretty well overall.
Good luck, and keep a bunch of rags at close hand... oh yes, the brand that I use (Molytec Australia
ep chain and cable lube) has moly disulfide in it... leaves a black persistent stain behind on your white deck
