Every kit I've ever used came with moly grease for the joints - either inner or outer. From a technical standpoint I can think of no reason not to use the typical CV axle grease (MOS2 fortified) that comes with boot kits or sold individually.

For your specific question, the Motul grease that you have posted the information should work well. They specifically state that it's made for universal joints and ball joints. The inner joint does not articulate anywhere near as severely as the outer joint so the stresses should be far reduced over the outer joint application. I personally would use a Molybdenum fortified grease but that's just my opinion.

Tripod joints take very specific and very expensive grease that is the reason it is not included with many boot kits. The Motul is not the correct grease.


All that said I do a lot of Tripods and looked for a long time for a suitable grease, after talking to Mola and Schaeffers I found a grease that works well and hold up long term in these joints. 219 SynForce Green NLGI 1, it contains a different moly that protects like MoS2 but does not clog the needles. NLGI 2 is not really suitable in cold temps.

What about Egypt's climate. The lowest temp had came over Egypt is about 8 Celsius (46.4 F), so i guess cold weather is not my issue or What do you think? My problem here is these type of greases you came up with are very difficult to find in my country, the best that i found is the Motul one. As temp. is more hotter than cold. So i guess NLGI 2 works fine or What do think? also to put in consideration in summer ambient temp reaches at 42~45 Celsius (107.6 ~ 113 F)

IIRC the Audi 80 uses a cross groove inner joint, very easy to replace and MoS2 grease is fine in those.

The Toyota dealer has no OE grease? I have run Redline CV2 in them before without any issues until I used it on some inner joints that have a more extreme angle stock, the housings developed excessive wear. Go ahead and use the Motul, the worst thing that can happen is the joint prematurely wears and you need to replace it

What about Mannol EP-2 multi MoS2?
