go to the auto parts store and get you these 2 things
Fast drying graphite spray.
mobil one sythetic grease.
You do not want to put grease on cvd's, it attracts dirt. I spray my hinge pins, cvd's, pillow balls, joint cups, axles, drive shafts, servo saver post. I use mobil one on ring gears, orings, building my diffs, not much else really.
The 2 things i mentioned are cheap and work very well. You can even get the graphite powder (for key locks etc) and ground the ball ends of your drive shafts.
Another good thing to use is oddonnell lube, it's a wax lubricant that is dry in which case i would put the o'lube on the actual cvd and spray the inside of the joint with graphite spray along with the axle or universal joint cup.
