CV grease revisited

[Doug]

I know this topic has been discussed, but I did a search and it looks like it has been 2-3 years since the last serious topic about CV grease. I was talking with my Swepco sales rep and I mentioned that a lot of people mix Belray with Swepco 101. He was shocked. He said there should be "one" grease that can handle the needs of off-road racers. Now maybe he is not as informed as we all are, but he brought up a good point. Shouldn't there be a product capable of handling the CV loads without having to mix two different greases? I think there should be and if it doesn't exist we should ask them to produce it.

That being said I'm curious about Swepco 103. It is supposed to handle higher shock loads, although it's temp rating is a little lower than 101 (375 degrees for 103 vs. 500+ for 101). Has anyone here tried the 103?

I'm actually thinking about putting four different CV greases in the four joints on the same car, run it hard through the nastiest whoops for a long time, then take outside temps of the CVs, then take apart the CVs and look at the wear patterns. We could learn a lot doing this. But I have a feeling someone may have done this before. Any info on past CV grease tests available online that you know of?

We run a 1600 car and have tried all the different kinds of grease. We use the stuff from Mckenzies called Moly, I think. I will have to look on the tube but I think that is the name. We use it by itself and have had no problems at all. We have tried Swepco in the past but it turns really chalky after the cvs warm up.

Would using four different greases on all four cvs be very telling? I wonder if there is a big difference between the inner and outer cvs. Maybe using an inferior grease on the less stressed cv would make the grease appear to be better.

Well we would have to do several tests to take out all variables. Time consuming but fun for sure.

Please post your results, I am interested in the outcome.

Doug, its a great idea, but lots of people have allready done this. I know on several cars I've worked on, our grease mix/blend has come from this real world testing.
You'll notice that certain greases yeild certain benifits, such as less wear, and some stick to the metal better.
Also, some of the greases can only take one heat cycle before degrading.
You'll notice that the longer you run the car, the more one grease will seem like a better option.
Don't remember the greases we played around with, but the most bada$$ stuff is krytox (sp?). Super heat tolerance, very $$$, its used on the space shuttle by nasa for some bearing lube.
Best of luck, try moly greases, mckenzies sell belray w/ moly. I personally never really liked the neo cv grease. That judgement came from being to easy to clean my hands after using it. I think its a good cv grease if you've got to use gas and brake clean before you can start thinking about washing your hands.

Belray. That is what we use. We have never had a problem with it. And it passes zjohnson's test for being a pain in the *** to get off your hands.

we have a good alternative- Jess

Not this again, jess.............

Anyway,....I use some stuff from CAT, called 'California Gold'. It's used at all of the high pressure points on their heavy equip. I've had really good luck with it in the 1600 classes, but we had some excessive wear when we tried it on my brothers' class 1. Only defense here was the cv's were used, not sure how many miles were already on them. I know my brother has changed to the swebco - belray mix and has great results. I use the CAT stuff on everything with the 1-1600, makes things a bit simpler. hope this is of some help.....

The neo Grease has been the best for us, as for using one over the other based on clean up I would want the one that was the worst to clean up becasue it will stick to everything that is going on inside the CV. We have tried a great number of lubes and that one has performed the best so far.
