what i use is high temp grease, the red stuff, and i take a drinking straw, fill it with grease, ussually just pushing it in the grease will fill it, then i take a left over chinese cheapo chop stickl and insert it into the drinking straw, this makes a style of syringe. now flatten the tip, insert it in the gap of the bearings, and squeeze a little bit in. repeat around the bearing a few times, spin it over, then clean up the excess with a rag. ill take pictures after my shower for you
