RCV Shafts wear and warranty

Hi,

I've got the dyntrac prorock 60 in the rear and the 44 in the front. I chose the rcv shafts in the front to get even more strenght and preffered them over the standard joints.

I installed my axles last year in May and haven't wheeled that much, because over here there aren't that many hard trails nearby. I went to France last month on my first real three day trip to the mountains. There I noticed when putting it in 4wd the shafts seem to click when the steering wheel was turned all the way to left or right. I know this is the first sign of wear to the joints. what I can't figure out is, that; the joints are greased several times since last year. I haven't used the 4wd that much, so there wasn't any torque on the shafts. And they didn't suffer much abuse. How come they start showing signs of wear so soon???

When contacting RCV; They want to ship me a rebuild kit, I could order one on their website and offcourse pay for it, 145$ for each side. Their warranty only supports breakage.

So I need to continue driving untill it breaks and then they will help me out with new joints!? I'm confused.

Anyone else experienced problems with these shafts in a short period?

Strange, normally the clicking noise starts when the joints wear out. I hope you're right, but I never heard the noise when I just installed them.

Well apparently the RCV's start to click when they have some miles on it.

The strange thing is that with other vehicles that have these joints, for example Toyota; when the clicking starts it means they wear out.

a little What is this noise? CV joint? 05 F150 - YouTube for demonstration

I didn't think they would wear ou this soon. And there is no warranty on wear, only breakage.

Mine click at or around full lock on the trail, started doing it about 6 months ago. On the street in 2wd I don't hear them. I grease them pretty well as well so I'm not terribly worried about it. I have prolly 30,000 miles on these.

What grease is everyone using? Did you guys purchase the expensive moly grease RCV sells, or regular off the self stuff from an auto parts store?

After talking to the RCV rep at the all breeds jeep show in york I ended up buying some valvoline synthetic grease with moly lubricant in it that is inteded for use in cv shafts that I was able to find at my local parts store.

I don't beleive the clicking in the shafts is a huge deal, yea it's an annoyance but they flat out work. I've beaten the crap out of mine and they jsut keep taking it, I used to go through ijointed shafts like crazy and now it's no longer an issue.

I would however like to get input from someone over at rcv on the matter.

I bought my axles second hand. I didn't get a tube of grease.

Mine started clicking on my second trip. I recently sent them back and they rebuilt them for free but mentioned that they had been oversteered a bit. The next trip out I broke an axle at the splines and after emailing a picture they shipped out a new axle, no questions asked, no hassle.

Well they're not consistent with their warranty, because I need to pay 150$ for each side. Maybe it has something to do with me living overseas.

I need to say that I had some trouble with my RSE rocksliders before and they shipped me a new motor for free. I also had a joint go bad with my Tom Woods driveshaft and received a new one, no cost and he added some stuff for free.

I guess I assumed as a company states; warranty no questions asked, they would cover this.

Well I know now I'm not the only one with this joint problem.

Strange that this thread came up. I was thinking of getting RCVs for my buggy, but 2 guys I know running them in their JKs had to send them back to get the Joints rebuilt when they were still pretty new.

Hmmmm, Maybe I will just stay with my original plan and get chromo shafts and CTMs - I know those last.

Chris.... mine's been clicking since god knows when. RCV had me send them in for rebuild (free), but it corrected nothing. I am not sure if it is the RCV or not, but you know how I wheel and I have yet to have any issue other than a constant question of why is your front clicking.

Between the warranty, silkiness at lock, and strength gains over a u-joint... the few drawbacks are WAY too small to keep you from running these.

They will go into my new front end.

I bought a set second hand as well. They were quiet the first couple trips then started ticking in 4WD. They were binding pretty bad after the second trip after the ticking started and I contacted RCV, they sent me replacements for free, and I wasn't the original purchaser.

I think I heard there was a slight defect in the original design that cause premature failure in the JK D44, but it has been corrected now.

As you are already aware, RCV Performance’s lifetime warranty does not cover wear. The clicking noise is a result of extra clearance from wear within the internal CV components, which can be accelerated by over-steering. We have heard your concerns over the price of our rebuild kits. We know you pay a premium price for a premium product, so we have decided to lower the price of the rebuild kits to keep maintenance costs at a minimum. Our goal here at RCV Performance is to offer the best products on the market and back it with the finest customer service possible. We do listen to your opinions, and strive to better our business by them.

Regards,
RCV Performance

Like you can see, RCV replied after I made them aware of this thread and their opnion was asked. Kraig also replied to me with an email, which stated

"RCV talked about this as a team and want make this right by you, can I send you 2 new cv joints, they will be greased up and ready to plug in and go. Please make sure you limit your steering angle to 42 degrees. Let me know if this option works for you."

Good quality products, deserve a good quality service.

He'll send me a tracking number tommorow, so the replacement items are on their way.

This story could help those who are still in doubt, what kind of shafts they want to buy.

Thank you RCV

If you end up going past 42 degrees add a washer to your steering stops and check again. Add washers until you no longer pass 42 degrees.

I have to say that I received a pair of brandnew outers with joints. Thank you RCV for that, but I am with you that they started clicking pretty soon. They're not broken or anything like that, but it is the first fase of wear. Before I put the new ones on the Jeep I'll check my turning degrees.

I'm still happy with my shafts, because they are reliable in strenght and that is wat I want when I'm miles from home doing a wheeling trip.

Can someone, who has the clicking noise, pull their shafts, pull them apart, and take a look at the splines on the end going into the CV joint. I just pulled mine to find this and wonder, was the clicking a slow roll to get this result? I doubt it, but am scratching my head how those splines could have been worn in like that.

I've started another thread with my specific issue, but am wondering if there could be a connection?

Here is what the splines look like.

couldn't be happier with my RCVs.

imagine my surprise, and I question how long it has been that way.

called RCV and a new boot is on the way! Thank you.
Once it gets here I will pull, check the shaft and joint re grease instal and be back in action.

And I beat on my RCVs 40" tires and a heavy pig truck. Awesome product, awesome CS, money well spent!

Is this on a D44? How many miles with the 40s?

Cool rig, by the way. Are those Sawzall brand half doors?:koolaid:

I thought a cv joint would be better at full steering lock. If a jk has stock steering stops there should be no wear problems started with the cv joint. The stock axle joint can handle it fine with a little bind.
I've been driving for a week with only the front drive shaft, and I assure you that the stock front axle shafts SUCK anywhere near steering lock.

I now almost lust after a set of RCVs, and this thread gave me some doubts, then put them to rest.
Yeah, let's go ahead and call it lust . . . :eek:

Normally the clicking comes from inside the joint. The problem you have is absolutely not good. How does the other end look like (inside the joint)? The splines are also round instead of pointy.
