CV Grease vs Normal GC-LB Grease

[nobb]

Does anyone know how CV grease is different then standard chassis/bearing (NGLI GC-LB) grease? I'm re-booting my CV joints and it's hard to find CV grease locally. Is it ok to just use a high quality moly based grease that's rated for bearing and chassis instead?

Thanks.

Go to NAPA,they sell it in their Precision/Moog/Napa U joints line.

I did try Napa and Canadian Tire. Nothing. The selection isn't as good here in Canada.

You can try this for a high quality grease and some of their technical information. Since you may not be using a lot of grease it might be worth paying a bit more for a good quality product.

Valvoline Durablend says it is suitable for CV joints. Is Valvoline Durablend hard to find where you are?

Never seen this anywhere local. I can keep digging for CV specific grease, but I really am curious as to why a high quality moly based GC-LB grease would not work.

Ask for pouches of CV grease (Typically black in colour) that came from CV boot kit.

Many places sell them outright. If not, at least those parts shops should be able to point you to the right direction.

GF AEV'd JEEP has $$$ rcv axles which are heavy duty CV joint axles. Their specs call for high quality moly grease.

I personally would use a high quality moly chassis grease without loosing a minutes sleep.

Only matters for taste.
I always buy the milk with extra fat. Usually 4% or more.

On another note, the milk in Switzerland is still the best milk to taste. Not sure what fat % but I think it is just the Suisse cows.

wrong thread......

I wasted several hours researching this a while back and came to the following conclusions:

Rzeppa joints (typically the large outer joints with six balls) are pretty forgiving as far as lubrication, but moly-fortified grease is recommended. Lots of options here, with most off-the-shelf options being a lithium based, moly-fortified grease (3% is common).

Tripod joints (typically the small inner joints with three needle bearing rollers) are not served well by the same moly-fortified grease. They typically want a lighter weight polyurea grease which can be hard to find. Aside from biting the bullet and buying the little pre-packaged grease specific to your manufacturer (i.e., Honda, Subaru, etc. typically offer two separate tubes for the different style joints used), the only readily available and inexpensive option I found was John Deere's multipurpose polyurea grease. It's thicker than what the manufacturers sell in the little tubes, but it's closer in composition than anything else I found.

For my son's Subaru, we recently used John Deere's moly-fortified lithium grease on the Rzeppa joints and their polyurea multipurpose grease on the inner tripod joints. Lots cheaper than buying the specially packaged tubes from Subaru.

I wonder how a moly grease with the GC-LB certification would work, as those are designed for bearing service. OEMs typically use two different greases for the inner and outer joint, as you have noticed. However the aftermarket boot kits only come with a single type of grease. Usually moly enforced type which is visually indistinguishable from a typical moly grease. They also tell you one packet of grease is enough for each side, but IMO I dont think it's sufficient.
