View Full Version : VIDEO : JL JOURNAL - How to Install 1350 Drive Shafts on a JL WRANGLER

01-23-2019, 12:55 AM
Contrary to what some seem to think, the factory driveshafts that come on a Jeep JL Wrangler are in fact, surprisingly strong. The rzeppa joints used are really beefy, the one u-joint that comes on the front driveshaft is a 1330 (bigger than a standard 1310) and although the tube walls are on the thin side, they more than make up for it with their very large cross section. In the past and on a JL Wrangler, I would have recommended that the front driveshaft be replaced after installing a 3" lift or more but thanks to the all new FAD system that the JL Wrangler comes with, there really isn't a need for it. Of course, on a 4-door Unlimited, the rear drive shaft is so long, you really shouldn't have any problems running it even with a set of 37" tires. That is, so long as you aren't running too tall of a lift.

Now, if there is a reason to consider an aftermarket, double cardan u-joint style driveshaft for your JL Wrangler, it'd be because you have a 2-door. Being that the rear driveshaft is so short, a 2.5" lift or more will cause it to sit at a steep enough angle that the CV boots will be in a constant state of pinch. Sooner than later, this pinch will cause the boots to fail prematurely and that'll leave the bearings inside to fry. Also, if you have a 4-door JL Wrangler and are running 3.5" of lift or more, you may want to run a new rear driveshaft as well and mainly because the diameter of the rear factory shaft is so big, it'll rub the side of your gas tank at a full flex. Because aftermarket driveshafts are made with thicker tubes, they can be made a lot narrower diameter and that goes a long way to help out in the clearance department. The same can be said up front as well especially if you're running shocks that allow for big droop. The narrower diameter of an aftermarket driveshaft will do a much better job of clearing things like your skid bar and exhaust cross over.

As you can guess, the last two reasons are why Cindy and I decided to upgrade our JL Wrangler's driveshafts to set of aftermarket, 1350 u-joint style double cardan driveshafts and in this episode of the JL JOURNAL, you'll get to see what it takes to get them installed. As an added bonus, we also included the necessary steps of how to set your rear pinion angle after the install as well. We hope you find our video to be helpful to you and if you have any questions, please let us know.

What Driveshaft Should You Get?First off, I would highly recommend that you NOT waste your time with a set of 1310 driveshafts. As mentioned, the one and only u-joint that comes on the front driveshaft is a 1330 and is STRONGER than a 1310. If you're going to make this upgrade, do yourself a favor and spend the extra money on a 1350. Second, I would recommend that you buy a driveshaft based on what u-joints it comes with and NOT necessarily based on brand. I personally prefer to use Neapco u-joints because they have always proven themselves to be strong and because they're made in the U.S.A. A good alternative u-joint would be ones made by Spicer. I would also recommend that you NOT get u-joints that are greasable being that they are hollow and tend to be weaker.

With that said, I personally prefer to have custom shafts made by my local driveline shop. If you play as hard on the rocks as you think you do, a local shop is something you will be using on a regular basis to have your driveshafts re-balanced and/or rebuilt. That being said, I have run JE Reel shafts in the past and would highly recommend them. At the time we made this video, Cindy and I were down in the Vegas area and in a pinch for time so, we decided to buy a set of Adam's Driveshafts and give them a try.

Like all our videos, this one was made to simply show how I personally like to install my driveshafts and with the hopes that it might be able to help out others. If you disagree with my methods or know how to do it better, I would encourage you to make your own how to video so that I can learn from it.

No need to get Adams unless you're in the area like we were. I mean, they're decent shafts but I would still recommend getting a shaft at a local shop any day of the week.

Like I always say, if you play with your Jeep as much as you say, you really need a local shop to balance and rebuild your shafts and on a regular basis. Might as well start a relationship with them now. :)

My local shop charges a LOT less and typically has 1 day turn arounds. I would have used them again but was in a bind for time with SEMA and the JLX around the corner. Don't get me wrong, they make a nice shaft and they were nice to work with but I'd rather give good advice than plug a company that I just happened to buy something from.

Again, if you have a shop local to you, I would give them a look first. If not, Adam's definitely makes a decent shaft.

These guys didn't know me from Adam (see what I did there :D ) and still treated me right. Best prices I've gotten anywhere especially with Neapco u-joints and they had a super fast turnaround too. If I had time at the time, I would of had them make me a set for Jet.

Yup, here's the thread in question:
https://wayalife.com/showthread.php/53962-NO-MORE-SLOP-in-MOBY-s-SHAFT-New-Custom-1350-Front-Drive-Shaft

Paid $369 for a custom shaft and built to my specifications and got it stupid fast. I paid Adam's a stupid $1439 both of Jet's shafts - that over $700 each! I won't say it's a rip off being that they were able to help me out in a pinch but it's hardly what I'd call a deal. It always makes me laugh when I see people who only buy based on brand name.

Good video, and per usual.

This video was for the JL but seems very similar to what I gather is done for a JK. Is there anything procedure wise that would be different on a JK?

I noticed when you checked the pinion nut rotational torque you had the tires on, I've read elsewhere you get better reading with the wheels off or even with the shafts removed. What's your take on that?

I'm not trying to setup gears, I'm just trying to find where things are at so that I can get back to that point later. Most people and even shops don't even do that much. It's just an extra step I like to do for my own peace of mind.

Oh, the install on a JK is the same.

This ^^^^ is what Adam's will need. Most shops will want something similar or the same. If you're running yokes as opposed to flanges, it'll be a bit different but similar. The biggest difference will be in how much you get charged.

Wow! That was a great video and you make it all look so painless. I do have a question about the control arms. Those JJ have the nipple for grease. I noticed you mounted both sides with the nipple up (I presume for ease of service). Does a half turn make enough difference that you would ever run nipple down (notwithstanding the greasing difficulty) to get a more even pinion/driveshaft angle?

Great Video Adams should use it as an official write up [emoji106][emoji106][emoji106][emoji106]

Very informative video! I don't even have a JL and I always watch your videos.
You guys rock!

Thank you. Truth be told, this video would help on a JK as well [emoji41]

Thanks for a great video! Had one question, for the rear pinion nut torque, you read 41inlb, will that be the same for all JLURs? I.E. do I still have to figure out what my factory torque setting is?

The preload will be different for every Jeep. As I state in the video, checking this isn't exactly required but it is a step that I do. I'm pretty sure that Adam's doesn't even include it as a step in their instructions.

Awesome videos, thank you! I've binge watched all your most recent videos, always learn from them.

This video was the first to help me understand the pinion angle adjustment out back.

With the quality of your productions, and the content, I'm amazed you guys don't have a weekly show on Discovery Channel or something like that!

One question with respect to my 2016 JKR, 2.5" lift, stock D44, with GEO brackets (AEV).
Planning a drive shaft for the front, and understand it's a trade off's for caster, flighty steering and pointing the pinion at the T-Case.

It is as simple as remove and install new up front? Possible of getting vibes in this case? Am I over thinking this one?

Thanks again!

The number one thing that will get you feeling driveline vibes at all is a driveshaft that isn't balanced and so long as you're running factory gears, 4.10's or lower, you may not even notice an unbalanced shaft. However, once you get up into 5.13 or higher, the shaft will spin so fast that any imperfection would be felt. Likewise, the more your shaft is not in line with the pinion, the greater the chance is that those imperfections will be felt even more. As you mentioned, caster needs to take precedence over the pinion lining up with the driveshaft but so long as your shaft is balanced and you're running about factory caster, you shouldn't feel any vibrations. Of course, if you were running something like a ProRock axle with it's built in 6į of caster, it's a lot easier to get your pinion lining up or very close to it.

Thanks for the video! It was very informative. I think I watched it 3 times before I installed my driveshaft and still managed to screw it up! My brain must have been on break when I assumed that loctite that was provided was a lubricant. Now I'm ordering new seals.🤪

Well, we learn by doing.

Huh, didn't think about gear ratio making the driveshaft spin faster....good to know. I see I forgot to note I am running the stock 4:10's.

Appreciate the explanation, sounds like with a good quality drive shaft that is well balanced, I shouldn't feel any vibes, so in theory neither should my transfer case.:D (I drive about 650 KM per week)

Cheers

Yup, right now, your front driveshaft will spin about 4 times for every one full rotation of your tires. With 5.13 or higher, it'll be more than 5 times and that's pretty damn fast for a shaft without any load and with a pinion slightly down from it. So yes, you should be good to go so long as your shaft is well balanced.
