Protek Premier White Grease for ring and pinion gears for the diff and Protek Premier Blue Oring Grease for shock orings. As for CVD's and universals on the driveshafts I use graphite spray because I don't want a wet lubricant attracting dust and dirt to those areas. The graphite spray dries very quickly and being a dry lubricant it doesn't attract dirt at all. Hasn't failed me yet.
