Here's the Spicer u-joint from Quadratec, the same part number applies to a bunch of different models and model years. I carry two as trail spares.

 

Most definately the wrong joint. But I do use those for the ft axles.

 

I could be wrong, but thought the Rubicon's had from the factory:

1310 U-Joint at diff
1350 U-joints at CV


Call Northridge 4x4 and order the JE real joints or stop by a local heavy truck driveshaft shop and pick up spicers.

I can't think of a single joint on the LJ Rubicon that would be different from a TJ.

 

Here's a really good overview of U-joints.

 

Non Rubicon 1310's

Rubicon 1330's

 

Appreciate that info John. It is great info. But I finally spent 2 hrs with Spicer on the phone. They're goin to fix the error they have listed for the 05-06 Rubicon LJ for the rear shaft. They said they have had dozens of calls from vendors letting them know that the 1310 joints they have listed for the rear shaft 585AA IS indeed incorrect. They are the HD 1330's old pt#5-790X. (2) 4 clips on the o/s 3 5/8 caps are all same size. I've read at least 50 different posts all over the Web various forums complaining same issues. Most resorted to napa etc. Matching them up or reordering till they got the correct one. So for those that own a 05-06 Rubicon LJ, 5-1330X are the correct ones with the 585AA rear shaft. You will also know by Spicer casting 539 VS 529 for the 5-1310X. Maybe one of our administrator can make this a sticky or something. There's a ton of people linking Spicer charts etc on here which is wrong for these specific years and model. Anyways... Just a note. P. S. Most vendor websites are also using Spicer info as I had made a dozen phone calls. P. S. S. These 5-1330X is a NON GREASABLE

 

Unfortunately Phillip, been beating this dog for two weeks now, and the Rubicon LJ is a different breed with the rear joints. Specifically on 05-06.
I'm still betting it will take some time to incorporate the fix. It was rampid though. I read at least 4-5 dozen posts all over the Web regarding the rears. Everything else seems to be fine.

 

AND, the 5-1310X is considerably smaller joint. I want a big joint
:-D

 

Good job

Ah-so - thanks for chasing that down, I'll make this a sticky in this section until we (me actually, it's on my to-do list) do a comprehensive FAQ. I run a Tom Woods CV rear drive shaft and I'm fairly certain the pinion end is a Spicer 760X as are the front axles.

I need to remember that in Jeep-land we have stock, mostly stock, or highly modified vehicles and making a blanket statement about this or that can be wrong.

Now my $0.02 about u-joints...

Quite a while ago for a few seconds I thought about going for the best and strongest u-joint (like CTM) but then again I would much rather have a u-joint break than damage a drive shaft or break a front axle or break something else more expensive.

 

I appreciate that John. I'm not an extreme wheeler, but i've wheeled the crap outa my Rubican over the years. Mine was 4 days old straight from the Rubicon plant, waitied 7 months to have it built, when Dino first took me out completely stock up in Uwharrie where I use to live. (now in Jacksonville)Ever since than, i've seen what a Rubicon can do. And if Dino recalls, that's where the 'Rubican' originated from. We took nothing but they advanced trails and i was hooked for many years to come. I just have not had the dough to put a healthy lift on. But thru the years, ive seen what it can do, and I wouldn't trade it for anything. It's a keeper. But now that it's seen some wear, it's time to replace a few things. It has really been good to me. First parts iv'e had to replace besides basic tune-up parts and another set of Mtr's. Anyways, I appreciate the sticky forsure. And p.s. I believe your 2 cents is correct, but I do respect the skinny pedal...so so far, that has worked for me. I gotta afford to fixit in either case..lol

 

So your saying either the yoke or the CV components on the LJ were machined differently to accept different sized U-Joints than the standard TJ?

 

Phillip

That is absolutely correct Phillip. Spicer told me they're actually considered HD 3/4 joints. Considerably larger than 5-1310X . But as I mentioned before, this only applies to the 05-06Rubicon LJ, the only 2 years it was built. I'm guessing because of the longer rear shaft/WB. Let me make a slight correction Phillip, I am NO way saying that all components on a Rubicon TJ are different, but the rear shaft 585AA on the 05-06 Rubicon LJ are different and are considerably larger and are HD. This is and was confirmed with Spicer/Dana. I don't know what other models are equipped with, just to be clear.

 

So what is different ? your saying it's not a 1330 joint like the other Rubicon's. 1310 and 1330 share the same cap size but the 1330 have a larger cross, what else is different.

 

You should probably go back to the start of the thread....and read from the beginning.....you've missed some info

 

Does the 1330X fit the TJ rubicon model?

 

In regards to your 03 TJ Rubicon, according to Dana/Spicer, no. That would be the incorrect joint for the rear shaft. According to Spicer/Dana, you're using a 5-795x non-greasable I/S snap ring joint on the ft and a 5-793x 1330 conversion joint on rear. But again, i'm in no way, the person to tell someone he does/doesn't have something on his vehicle. That's just not me. This info came from Spicer/Dana charts, which didn't help me. Nor did the info I rec'd from Quadatrac or Northridge. I was being told that I was supplying them the wrong information and that they sell to hundreds of customers. But I knew what I had and found the info from DrivetrainAmerica.com from Adam who was outstanding as we spent significant time with Spicer and their Technical Team. The end result was Superior service and communication. And the correct joints with an understanding that a revision will be in the making. As this will be a large task considering there are ALOT of Vendor/suppliers of Spicer that are utilizing some incorrect information from Dana/Spicer charts throughout the web.

 

This just happens to be on another Jeep Forum

Re: Rubicon front driveshaft?
So now it's time to do the Rear. Does this (spicer part number) chart look right. This was the only reference showing a different number for the 2006 Rubicon LJ.

[Chart removed do to inaccurate data.]

5-785x = 5-1310x
5-790x = 5-1330x

Some people are catching on that some of the info is incorrect.


and here's another recent one.

This catalog page also lists the wrong spicer part number for rear driveshaft, 2006 Rubicon Unlimited.

But Mr Canfield, is planning on a sticky to help some of us out. lol

 

Installed

Got my new Spicer Joints today from DrivetrainAmerica.com and installed those puppies. Rear humming/ticking/vibes, GONE ! Happy camper. :grin: Now just gotta plan to do the rest at a later date.

 

Great report!

 

And I appreciate the folks that helped along the way. You know who you're :grin:

 

Great work...saved me from a confusing headache

 

I had the same problem getting a u-joint for my 2005 Unlimited Rubicon rear drive shaft. I went to O'Reilly and they looked it up in their system and I bought it. Anyhow it was the wrong size I returned and I brought my original u-joint with me and every part number they had was not the correct u-joint. Long story short I left there with a u-joint that fit and it was u-joint listed for a Jeep liberty. The P/N is a Precision 354 my intent was to get a spicer but none of the local shops carried it. For what it's worth the original u-joint that O'Reilly sold me was a bigger diameter.

 

Old thread but valuable information.

O'Reilly's computer shows a Precision 369 which is only 3.218". Way too narrow. After a lot of research and looking at this thread it's the 5-1330 alright which in fact checks with the Precision 354 at 3.62".

I'll be buying one and installing tomorrow. I will report back after my jeep is back on the road. ?

 

For sure.

I didn't have the time or the desire to mess with mine so I took it to a local driveline shop a couple months ago. Long time, well established, busy driveline shop, always a few Jeeps in the parking lot.

They ended up doing all the head scratching and figuring out how to get a Spicer joint that fit, which it turns out they didn't even have in stock, and told me about it after the fact. None of their Spicer application charts or documentation had it right for the '05-'06 LJ Rubi.

I found this diagram amazing! Answered pretty much all my questions. This should be the definitive answer for what Ujoint goes where.

Good site. Thanks.

 

I put the 354 in and it seems fine. The bearing cap has a weird zerk looking thing and a came with a screw to plug the body of the u-joint where a zerk would go. Confusing. I just found a zerk and put it in the body of the joint so I could grease it.

Btw, the u-joint that I pulled out had "352" on it.

That "weird zerk looking thing" may have been what's called a grease port meant to be greased with a needle adapter on a grease gun. Just make sure the zerk fitting you installed won't get sheared off with movement of the u-joint.
