RCV Axles

Has anyone on here broken the RCV Rubicon D44 shafts yet? Just curious, I run 39.5 Iroks, not sure how they will hold up. They are doing fine so far on mine.

I cant say that I have seen anyone break an RCV.

I did hear from over on pirate that a guy with a d60, RCV's & something like 49's failed one. I also heard he was pushing 500+ HP?
whether this is true or not?

I've heard from my local offroad shop about some RCVs breaking in a JK44. However, it was due to a bunch of mud and water (and presumably not greasing them afterward) that wore them out real fast.

I think that the RCV axles are the last thing you should worry about when wheeling 40's on Rubi 44's. Time to step up to big boy axles for sure. (and I dont call 5 lug 60's with rubi knuckles and ball joints big boy axles) Think of Rubi 44's with 40" tires as a hand grenade, with the safety pin pulled, and the handle secured with 10 year old scotch tape.

Ran the RCV's in my 44 with Iroc 39.5's for about a year, never broke them but had the notorious turn and clicking noise problem.

not sure but is sound like what happens to front wheel drive cars with Constanc Velocitry Joint axels. (like RCV but small and weak) when the CV joint starts to fail. when you turn rignt of left you hear the koint click.

my old subaru did it.

Steering stops.

Did you check your steering stops? Was it only at full turn? Thats one thing RCV warned me about.

Not a grease problem. It's a design problem. Just call Sean, no wait, he wont tell ya. Call and ask to speak to someone else and ask them if they have started clearanceing the bell to stop the clicking noise. But, that's not the real problem with them either. The real problem is in the cage design inside the cv joint itself. They tried to tell me my steering was causing the problem but, I built a brand new dana 44 that had never been tampered with. I took the liberty myself to disassemble the cv and found the cage to be the problem. Oh, did I mention they warrantied 2 sets and the third set Sean sent it took him 3 months to send. I had three sets of rcv axles in my 44 in a year.

Do a search on here and you'll find that there has been several people have problems with clicking on the rcv's.

Do you think it is all the rcv shafts or did you have really shitty luck? Saying that I have not had a problem, but you went throught three sets for a reason. Is there a way to fix the cage yourself or does it need a whole new design. Just curious. By the way love the build you got going.

FWIW, I've had my RCV's on for a year and change now, wheeling with 37's and have had no issues. Your mileage may vary though.

My 08 jk is for off road use only. It has a little over 7000 miles on it and I bought it in October of 07. So another words I wheel a lot.

Do a search on here and you'll find that there has been several people have problems with clicking on the rcv's.

i am sure everyone has a different story to tell and i am sure yours is mostly true but here is mine.


i too had the clicking at full or close to full turn. stuff wears out and stuff breaks, its just how long before they do. i called up the company and talked to greg at first. long story shortened i sent in my shafts the next week on monday. they recieved them on a wed. they fixed them with new cv joints and sent me two new boots and a tube of grease. i got them on thursday (the next day).

i called told them exactly what the issue was and i run a 38 X 14.50 on spyderlocks. they don't care about the abuse you put them through they just fix it. i ran mine for about a year and half before they clicked. i belive they would have lasted a lot longer but i didn't like the click. my shafts are still perfect. i spent a woping 30 bucks to ship to them and i ended up with a nearly (same shaft is all) new 1k set of axles again.

i have twisted one spline in the rear and bent 4 flanges with aftermarket shafts. the front has made it through all of those and would still be going strong if i could of lived with the click.

i personally can't think of a better manufacture right now. i am so impressed with rcv and kraig, greg and john that i want to give Rcv props. i called them on friday and told them how happy i was with them. thats what a company that charges a premium for some good stuff should do. you can slam me all you want and tell me i work for them but i don't. i am not to active on here, but this company deserves some credit.

if you have a issue be honest (they don't care how it happend) and call them up to send it in. if your a better man then me you can even have them send you a rebuild kit (for free). great product and a company that cares. way to go RCV!!!

I ran 37 creepy crawlers on a d30 with rcv's. They would still be on my jeep if my daughter hadn't wrecked it and bent the axle. I swapped out to a d44 and running 37's and I do get the popping noise but as long as it's still digging who really cares? I highly recommend them.

I have a jeep and it goes over shit.

One of the few universally admired vendors, if you want 'em get 'em. If I had known they made them fro Spyntec conversions they'd be on my rig right now instead of the Superior evos & CTMs.
