Planman,
Did you see above where WOL made the comment that some "Chinese" ones were tested. They tested just as strong; however, they had poor QC and several failed.
I'd suspect the same thing is going on with the gold seal.
Would make for interesting fodder to have them analyzed. Including sourcing one that did break and analyzing it.
Edit: heh, WOL was faster than I. He must be on a real computer and not an IPhone.

for a guy who is in the need of drive shafts... my f'ing head is spinning. So much to digest... I am going to have a melted cheese sandwich and think some things over
*thanks for the heads up that dana 60s require shorted shafts! thought I would be able to buy them once*

The JK market is lucrative for driveshaft shops/manufacturers--more lucrative than the TJ market ever was...
...No one wants their customers to have a bad experience--especially because of forums like this one. Only a few bad experiences, if expressed on a forum can make it look like it is the norm rather than the exception.

I have to confess, that I have never considered running a JE Reel driveshaft because I saw WOL blow a JE Reel flange at EJS on Metal Masher a few years back, and I read experiences that people had with balancing issues. These may have been rare exceptions, but the personal anecdotal experience combined with what I read lost JE Reel a chance at my business. (And...I own 3 JKs, with dozens of friends who own JKs.) Still, there are many people I respect who have run JE Reel for years and will likely never change.
Regarding balancing issues, yes, there were in fact a lot of people who had them in the past and, from what I understand, a lot of that had to do with the inferior u-joints he was using at the time. However, unlike manufacturers that you would choose to have so much confidence in, JE Reel chose to bite the bullet, make changes and, offer his customers a better product. Personally, I would prefer to put my confidence in a company that can learn from it's mistakes rather than one that insists they can do no wrong and, tries to bully people like me with the hopes of hiding the the truth. But hey, that's just me.

well, without making you read the whole thread, most any shaft with spicer or neapco u-joints is what i would recommend. i personally prefer coast or je reel because they come with these u-joints without having to pay for an upgrade and, offer them for about the same price as their competitors. being that you're running 38's, i might recommend 1350 shafts if you play hard on the rocks but, if not, 1310's will be fine.

Now that you mention it, I do seem to remember that it was the double cardan piece instead of the flange because you went back to town looking for a take-off stock rear driveshaft you could use to finish the week. If I recall correctly, it was a 1310 OE replacement shaft that mounts to the stock flanges. I might remember that you were surprised that the double cardan piece broke instead of a u-joint.
At the time, I was surprised at the failure because I did not have a full appreciation of how heavy a modified 4dr JK can be on 37" Toyo MTs with beadlocks, plus armor and gear. Most of the failures I had seen before that involved more tire/wheel spin, more aggressive bouncing/bumping, or significant binding with axles locked in a rock garden.

Since then, I have driven that sand ledge several times in my 2 dr on 40s and in our Suzuki rock buggy. It is a fun obstacle.
I read parts of the thread several months ago about the guy from NC who was running a 4" lift on a 2 door JK with stock arms and a TW shaft. When it eventually failed do to incorrect pinion angle, he slammed Tom on a weekend on the forum. Teraflex and Clayton came to Tom's defense. It was ironic as to how the guy did not realize how his thread made him look like an ignorant kid. It was kind of embarrassing. He relied on the suspension manufacturer saying rear upper adjustable arms were not required with his lift and ignored the driveshaft manufacturer's information about how to adjust the pinion angle.
Maybe Tom has sold 100,000+ of his proprietary joints over the years. I don't know, but they seem to have been among the most popular since I bought my TJ in 04--at least in magazines, on forums, and what I saw in person.
I've googled to try to find reports of premature u-joint failures in recent history. I'm just not finding much in results except for a couple failures because they had bad pinion angle adjustments or they didn't service/grease the shaft and joints.
What percentage of his u-joints in JK shafts to you believe are low/out-of-spec quality?
I suppose if Spicers are less money, his shafts would cost less if they were ordered with Spicers.
My intent on the forum is to learn and to share what I have learned.
I would like to know if all of the sudden a high percentage of Tom's u-joints are failing.

I need to buy a pair of 1350 shafts this month for our 2nd 4 dr JK after I install a pair of Currie RJ 60s under it. It will be on a 6 speed with 5.38 gears. So, they need to be well balanced. I am thinking I'll switch my 40s to that 4 dr, but am not so sure about running a semi-float rear axle with 40s on a 4 dr--even if it is a 60. I may run 37s on it instead of the 40s.

I would not expect you to know that I have a full sponsorship by Calphalon Panini Grills (photo evidence provided), it is the only grill I deem suitable for my hardcore cheesing and the only builder that fully discloses all materials sourced in its construction (caveat: because of the rules of my contract I cannot disclose these materials or sources). I would expect that in your 43 years of so called "lunching experience" you have experienced only lesser quality made sandwiches by your, laughable at best, "PAN FRIED" comment. This narrowly and definitively defines your experiences. I hope only to meet you along the grill one day and we shall then settle this like gentlemen. Good day to you and your "pan"

For whatever it's worth, I had talked to Jim Reel a few months back about u-joints and asked why he uses Neapco. And, what he told me was an interesting story about how there was a time a few years back that he was approached by a company that wanted to sell him high quality Chinese u-joints. They assured him that the quality of the u-joints would meet or exceed what he was using and for a fraction of the price. In fact, the savings he would see would be significant enough that it was hard not to give them a try. And so, he asked for a few sample so that he could have them tested. And, when the results came back, he was truly amazed. Needless to say, he decided to start using these u-joints and, for a while, all was good. But then, over time, he started to get more and more complaints regarding his drive shafts and the u-joints failing. Suspecious, he decided to take some of the u-joints he had and do some random tests on them. What he found was that while a lot were still meeting the standards he was promised, more than enough weren't and it became clear to him that continuing to use these u-joints would not be right. In the end, the problem was in quality control and, while some were getting lucky, more than enough that weren't. And, rather than make his customers take the gamble in what they get, he decided to bite the bullet and just use what he knew was right, regardless of how much profit he would loose. Needless to say, JE Reel is neither as affordable as Tom Woods nor as popular but, at least if you get one of his shafts, you know that you will be getting one of the most high quality u-joint around.
Having said all that, I would be the first to tell you that I used to say that Spicer u-joints were made in America and, after being presented by some reasonable facts from reasonable people, I have long since changed my tune and no longer say as much. Does this mean I won't use them? Of course not. Clearly, whoever makes them and wherever they are made, a higher standard of quality control is enforced and the proof of that is in what I've seen on the trail. This is why I still recommend them or Neapco. As far as Gold Seal u-joints go, believe what you will but I simply cannot make this stuff up. Why a company would continue to use them in spite of what they know is beyond me. That, or the only thing they are most concerned with is making a buck off of you.
