RCV grease alternative

Ok since fucking RCV wants 40 bucks for a tube of their gold. What are you all using for a replacement for RCV grease?

i use theirs. At 2-3,maybe 4 squirts every 3000-5000 miles, it lasts a pretty good while. But, yeah. It is insane ho much ( and many) greases it requires to keep a OHV on highway and off collectively. I have 3 separate grease guns with crazy expensive RCV, Synergy Mfg and one with some redNtacky or the farm green loaded in one , each of the 3 of them, as I type this.

If you try to use an alternative, you probably wont save much. It'll be some high pressure,hi temp molybedenbumediumamum sh*t that costs an arm and a leg . Then they maybe can say no lifetime wrrnty?
Red Line 80401 CV-2 is one type that might be suitable.

Looked at that one but it is red and I am sure that RCV would say no go on warranty stuff.

I rebuilt mine last spring to the tune of almost $300 because explaining the clicking after spending over $1000 on axle shafts is almost embarrassing. They got enough grease that it'd be coming out the boots but still started clicking the second year.
Better not happen again for a long while.

This is the #1 complaint for RCV shafts. You cant avoid it and they will start to click again. It's annoying AF.

They're considered a wear item, they're not broke so no warranty. I was told they wouldn't fail catastrophically before my last 30 hr trip to Moab which they didn't. They only click on tight turn in 4WD. Still annoying for $1000 + axle shafts but they're smooth. Look good with the Reid's also. I may consider them for the LJ build.

it is just the balls clacking as the carrier inside rotates, yeah? I thought they were supposed to make a small amount of clack clack clack just by nature of design? .mine has a barely audible click when I manually rotate the wheel on jack-stand and diff not locked , but not when I am driving it.

If this subject is a whole can of worms, let's save it until Monday, agreed?

Yes, you will feel or hear the balls moving inside the cage inside the joint as you turn the wheel by hand, with the vehicle on a jack of course. What happens is the ball bearings wear against the cage that retains them. As the tolerance increases, the noise increases. At some point they will fail as the ball will escape the cage and then it is a shit show. Or the cage will crack from the extra stress.

Personally, I will never buy another set of RCVs. They are too much hassle. They sling grease everywhere. They wear out. Replacing the cage and bearing is a PITA. And taking the axles in and out can cause a leak in the inner diff seals. Its just too much trouble. I like the strength. But the other crap you have to put up with is not worth it to me anymore. Next axle build will be chromo shafts.

I use the RCV grease. Sure it's expensive but seriously man, after spending $1100 on shafts what's another $40, lol!?!? I'm still on my first tube of it after almost 4 years I don't think I'll be buying another one anytime soon either, just buy the grease they say and use it! You already made a heavy investment in the shafts why not protect it as best you can?

I have had my RCV's for like 60k miles. Greased 2-3 squirts every oil change, say 5k miles, and steering limited to less than 45 degrees per their instructions. No clicking yet. A couple months ago I got the red rancho knuckles and they won't limit the steering as much as what I had before. Hoping that the dreaded clicks don't start up now!

Overall I'm a happy camper with these shafts I have put them through their paces and they have delivered so far with no issues.

( those are about the two most opposite opinions of RCV shafts as is possible, heh.)

Perhaps I was not clear. If someone wants / needs the extra strength and lifetime warranty (except for wear items) of the RCVs, then by all means. They generally hold up pretty well. But they are not a "forever" product. For me, I just want to try something a little less strong, (maybe, or maybe not) that does not require as much futzing with. I doubt I would ever break a chromo shaft.

I don't disagree that they are a great solution for some. Just know what you are getting into. Its not a buy it and forget about it product. I hope yours never start to click. You will see what I mean if they do.

so, I'm a pretty big proponent or fan of products by CRC . I sometimes feel that I bathe my Jeeps in 242 from them but that's not why I mention the brand ; I came across this and have no idea how much it costs but you can. I am sure I've seen this at O'Reiley's as well or maybe it was NAPA. Certainly worth looking at since Most of thier stuff is high quality but affordable,USMC

I feel the same way, they nail you enough with the cost of the shafts, they have to quadruple the price of the grease also ? When I rebuilt my Warn winch, I called them to find out what grease I should use inside. They told me to get AeroShell grease,33MS. It's a synthetic grease for aircraft containing Molybdenum Disulfide. It's Mil grade and Nato grade. I doubt there is a better grease out there and it was a fraction of that price. I hate companies who nail you coming and going.

That grease is bad ass. I have a tube I used in rebuilding my warm winch. It appears to be thin for the application of RCV's. Either way I have used it on all kinds of stuff.

I also have rcv shafts that click and it's definitely annoying. I did take the time to rebuild the drivers side with .001 bigger balls that rcv sent me and they still click... love how they perform, but not the noise they make. People look at my Jeep and ask if it's broke when off-roading all the time. Gets really annoying for the amount of money they cost.

I was fortunate enough to learn of this upfront and never purchased them. I feel as if half the desire to own these for most folks is that little orange boot, lol. Otherwise is there really that much of an advantage from these to a good set of chromollys? Has there ever been a situation where the chromoly shaft couldn't hang but these could? There is already enough shit to mess with on a jeep as it is that the last thing I need is another specialty joint to keep grease in and have it cost a fortune on top of all that. Out of place noises bother the living shit out of me, I dont care how much stronger these are I would never run them for that reason alone. I would never be able to tell if its just normal or about to shit its guts out.

There is absolutely no bind when fully turned and in 4WD with these axle shafts. The rebuilds are pricey and annoying as fuck for the cost. They also have cool shirts.

I've been in situations with front turned by about 40į into an overhung ledge that was about a foot or two taller than my front tire/wheel and the RCVs didn't flinch when I moved it slowly but persistently frward and up over it.
I NEVER would have even attempted to surmount that large of an undercut or try to press into it that hard with ujointed shafts ,even chromoly with superjoints I would have squared up first .
That's the advantage, along with the orange boot ,to RCVs .





(The "orange boot " was me joking. Someone , I think k @ExWrench maybe ?, Painted their boots 'cuz they look showy and gai. )

I missed that part about the boot. I have seen others going on about it though.

So someone correct me if I am way off here but isn't an RCV basically an rzeppa style joint? Why are they so strong in this configuration but not in a driveshaft?

The boots can't handle the RPM of the driveshafts.

I did a search for RCV problems the other day and a link to Pirate4x4 was very informative, with additional links within the thread that I clicked open. No one there is bashing RCVs. Well, that's not true. They're bashing the shit out of 'em on the trail, and the RCVs keep on rollin'. High speed desert, monster HP crawlers...things that couldn't possibly be legal anywhere but in competition.
What do they have to say about RCVs?
Don't over steer them.
That's it.
That's the only thing they have to say that could possibly even be remotely construed as negative.
Guys are blowin' out the cages, twisting shafts, whatever... RCV stands up with their warranty, no questions asked.
These guys go on to say there's no way in hell any other shaft would have survived, either, and more than likely would have broken many more times.
Bang for the buck? That's your call.
