I have searched all over and haven't seen much info on CV greases. Off-road is a strange application. They use VW type plunging CV's inboard and outboard, often don't have water-tight boots (sometimes leather or fabric non-rotating and loose on the axle). The CV's operate at large angles, high loads, slide the splines to get more plunge, and all of that adds up to high temps that will fry most greases. They are also cleaned, inspected, and repacked often. Many people seem to use a 50/50 mix of Bel-Ray Molylube 67700 Anti-Seize and SWEPCO 101 Moly Grease. The Bel-Ray doesn't say anything useful in the MSDS and I couldn't find one for the SWEPCO. Here are the blurbs from the manufacturers.
Bel-Ray Molylube Anti-Seize #67700 NLGI 2 A non-melting anti-seize lubricant designed for Extreme Pressure, heavily loaded applications requiring low breakaway torque. Virtually waterproof. Useful temperature range -184ºC to 399ºC (-300ºF to 750ºF). General Industrial Lubricant Mineral Oil ISO VG 460
Does anyone have any more info on these greases? What is "LUBIUM"?(any guesses?) They both say non-melt. Does that mean Bentonite? What out there (besides Krytox) would work better?
SWEPCO 101 Moly Grease * Non-melt grease that will not melt at any temperature * Contains the technical fine grade Molybdenum Disulfide (Moly Powder) * Optimum performance range is -30ø to 500øF (-34ø to 260øC) * Withstands up to 500,000 pounds per square inch of pressure * Contains SWEPCO's proprietary anti-friction and anti-wear additive, LUBIUM
