Installed them in my 08 Rubicon a couple weekends ago. I personaly did not care for the instructions I guess they are supposed to be universal but all but one sentence, and all the pics from what I can tell is for a TJ. (The only Yk sentence in the two page instructions is in red letting you know you don't have to remove the knuckle or do any grinding.) The instructions show a tube seal being used and it is not included with the over $1k shafts. So I used my oem tube seal off of my original shafts along with the two plastic mud inserts that go inside the shafts next to the axle seal.

For those who have these axles or even done this install I have some questions,

Step 6 mentions the CV having a needle tip grease fitting, has anyone used this grease fitting? I didn't see one on either one of the axles CV's.

On my install the end of the boot is just past the top of the knuckle bolt heads (that they included) the boots do not cover near as deep as the ones shown in the TJ instructions. My drivers side boot somehow got grease on the outside of it after the first day of driving but after wiping it off it has not happened since. I think there may of been too much grease around the CV initially. Anyone else had this happen?

Sunday while playing in the snow the passenger boot came off the CV and basically burned into the oem tube seal. I used the tool RCV furnished to put it back on after I noticed it after returning home. Luckily their boot is tougher much tougher than the oem tube seal or I would be haveing to pull the axles to replace it. I guess I will be packing that tool in the jeep from now on.
Has anyone else had one of their seals come off while 4bying in the cold?

Thanks in advance for any input on my first thread.


For anyone else planning on installing new axles my instructions listed no torques so I used...

That right there would make me hesitate to install this type of joint until it can be determined why the seal came off.

Can you take some pictures of your seal from a couple different angles?

 

Mine gets driven in -40 C so I want to know if it's affected by cold also.

 

There are no pics of it when it was in that condition. I am not that concerned worried about it, no problem posting pics later this week though.

I wonder why there is no positive grooves machined in the shaft that would assist the boot in staying on that would also give indication of it being on fully.

It very well may of been my install for all I know but it stayed on for the better part of a week prior to that happening. I am considering making a two piece bushing to put on the shiny part of the shaft that would work as a stop in the remote chance it happens again.

 

That would work, providing the seal doesn't have to move a little on the shaft.

Make it out of something softer than the axle shaft. Coat the contact surfaces with silicone to prevent corrosion under the two pieces.

 

Didn't get in pics today but... Stopped by an alignment shop and they varified all is well with the tire alignment. (The tires seemed like they are loading up at hwy speeds.)
While I was there I seen a jeep mag that had another company's version of the RCV CV axles in it. And their pictures where as plane as day. (Just incase I overlooked seeing the zerks during installation.) I jacked up the front end so the tires where off the ground, turned the wheel all the way to the left and rolled the front right tire looking for the zerk/needle greese fitting. Nope not there all that is there is a lazer engraving of the RCV logo. Then I turned the steering wheel all the way the other way checked the right tire and once again no greese fitting just the logo engraving. Instead of the CV's being shiney metallic like the ones shown in the instructions and in the magazine I looked at today they are black. So I guess I am going to have to take off the boot and add grease a couple times a year to be able to lube them as the instructions call out. I am now irritated with these axles as they also had axle grease around the OD of the boots today which I keep wiping off them as well as the steering knuckles. I have buyers remorse and will probably end up buying a Ujoint style aftermarket axle after this season. There is no way I am the only one this is happening to.

 

Just so you know I sent this to the owner of RCV hopefully we will get some info from him.

The zerks are on the end of the axle, you need a needle adapter. This is in the article in JP magazine.

 

i know there are zerks on there, ill try to find the pics i saved from online.

 

here is the JP article:

jpmagazine.com/techarticles/drivetrain/154_1001_rcv_front_axle_shaft_kit/index.html

here is a pic where the grease fitting is, just like Alaska said, u need the needle adapter for the grease gun. as for your boot, who knows, they have u break it they replace it policy, so see what they say, maybe u just another boot, they are only $5
