I am considering mixing up my own CV grease, as I've been unable to find polyurea based grease with molybdenum disulfide in anything other than expensive little pillow packs.
I believe most of the OEM Rzeppa CV joints are packed with polyurea/moly grease due to its ability to remain stable for many years and many thousands of miles. In essence, most of those bearings need to be greased for life when they leave the factory.
Virtually all of the aftermarket CV greases are of some other base (eg., Redline CV-2 is calcium, Swepco 101 is bentonite, Valvoline is lithium). These may all be fine/superior for racing applications where the grease will be replaced before it can deteriorate, but as a regular guy who keeps his cars until death, I just want to be able to service my vehicles once and hopefully never need to pull those joints apart again.
I can buy fine grade MoS2 powder for $3/ounce, and John Deere sells a decent quality polyurea base grease for $4. Each 14 oz. tube would require about 0.7 oz. of MoS2 to make a Polyurea grease with 5% moly. Hence, for about $7/tube, I can service my CV's with a longer lasting grease than anything I've found commercially available.
Any thoughts?
