For those of you who are new to working on Jeeps, ones with coils and a 4-link suspension system or are just plain curious, this episode of the JL JOURNAL, we'll give you a close look at what's underneath the Jeep JL Wrangler Rubicon Unlimited and with a 3.6L V6 Pentastar motor. Some of the things you'll get to see include the various components that make up the steering system, suspension system, drive train and skid plates and you'll even get to hear how some of them compare to what can be found on a JK. We hope you'll find the information in this short video to be helpful and as always, please let us know if you have any questions.
JL JOURNAL is a WAYALIFE Production with a focus on the all new Jeep JL Wrangler. This TH-cam video series will highlight every aspect of our Jeep JL Wrangler and of course, all the adventures that it takes us on. We hope that you'll follow us along on our journey.
This is real reviewer. Better than the other guys just reading off of a spec sheet and no idea what they are talking about.
Just trying to share what we can see :)
Best JL suspension and steering explained. Clear and easy to understand for the novice.
Thanks a lot!
Glad it helped!
I hope to buy my very first Jeep (I'm 61) later this year. Have learned so much from your channel! Thank you!!
We're so happy to hear it and congratulations to you on getting your first Jeep!
Excellent presentation. Thank you for sharing your vast knowledge.
Glad it was helpful!
Sir you are AMAZING! I’m trying to learn all this stuff alone and it’s so hard to find easy breakdown videos. I’m so glad I found yours! Subbing because I’m sure you have more useful videos for my needs!
LOL - thank you. Truly flattered you would say as much and I'm so glad to know that our videos are helpful to you 😊
AGAIN !. These are some of the BEST most INFORMATIVE videos out there. I am definitely a subscriber
Thank you, we're so glad to hear it :)
Excellent Video! Jeep Front End Suspension and Steering for Dummies (or new Jeep owners like me). Keep these videos coming!
Glad to hear you found our video to be useful 👍
Just bought a 2018 Jl rubicon. Really enjoying your channel. Thank you.
So glad to hear it and congratulations to you :)
Good driver and good technique.
Looks like I am going to have to get back into Jeeps, love the JL! Great video as usual Eddie!
Awesome, the JL is way nicer than anything you may have driven in the past :)
Great video. Enjoyed it. Really lived your last chance canyon video. Brought back some wonderful memories
Thank you, we're glad you enjoyed it.
A gearhead that correctly uses the word "peek" instead of "peak"? Bravo, sir.
LOL!! Thank you :)
Once again, an exceptionally well done presentation all the way around, Eddie! I long pondered why Jeep didn't offer free-wheeling hubs on the JK's. And, frankly speaking, I'd prefer freewheeling hubs (Warn brand for me of the pre-spring loaded variety) to the electronic device the new JL has. Yes, I realize with the "old-style" freewheeling hubs (unless one opts for the "automatic" type) one has to climb out of the vehicle to manually turn the knobs on both hubs to either "Lock" or "Free." But, unless someone abuses one of the hubs, or his an obstacle, these old manual hubs should easily last the life of the Jeep. Freewheeling hubs saved fuel (about one to one and a half MPG on Series IIA & III 4-cyl. Land Rovers); they also reduced drivetrain noise, as I'm sure you are aware. I'm going to need to do more studying on how the electronic disconnect works on the front axle shafts. Again, your presentations, explanations, and your wife's work with the camera are all first-rate. Thank you both very much for being such an excellent resource for Jeep Wranglers and their owners!
Love the beefed up steering components, coming from a TJ owner...that thing looks like a beast
They really are a big improvement.
Eddie, that was an excellent video. BZ. Looking forward to our 2020 JLUR to arrive.
Great video!!! I wish I would of waited 2 years before I got my JKU. Thank you Wayalife!!
Nah, what you have is great too and you've had 2 years to enjoy it.
I'll pile on - AWESOME VIDEO. Really informative. I subscribed!
Thank you! So glad you found our video to be informative 😎
Very cool showing the steering.Def better than a stock jk.Hopefully that beefing up also included the ball joints.Just because ive replaced mine a few times now.
Not sure about the ball joints but like you, I do hope they're a bit beefier than what we had on the JK.
Would love to see this new Beast off roading to the places like his big brothers done years ago....love it...
Thank you for let us know abouth the new monster jl this is my favorite video and the first video that explain what is going on under the new jl tks and good awesome video 3 thumps upfor you and your nes jl 👍👍👍
Thank you, we really do appreciate it :)
That really looks nice! Lots of beef everywhere and I especially like the aluminum parts. Nice upgrades on the new JL!
That suspension looks like it should hold up very well, as opposed to the older JK and TJ/LJ's.
They're definitely an improvement over the JK and the TJ
Nice simple overview Eddie! FYI, that's called a 5 link, not a 4 link with a track bar. 4+1=5 links 👌
Just want you to know that your channel inspired me to buy my first jeep last week. 94 YJ with a 4 banger. Might have to run up the hill and visit you next time I head to Reno!
LOL!! Technically, you are correct. However, there are Jeeps that came with leaf springs and a track bar and then there are custom 3-link suspension systems that have a track bar being that they're not true triangulated 4-links. I was just trying to be clear about things and apologize if I got it wrong for you.
Great video man. I can’t wait to get my first new Jeep.
Thanks! Once you do get one, be sure to post up pics of it over on JLWRANGLER.com
Awesome video double 👍
Thanks 👍
Dream garage your jl is home, nice video WOW!!!
LOL! Thank you :)
Fantastic overview. You REALLY know your jl and the jk that preceded it. Very cool and I’ve subscribed some time ago now.....my only complaint is that I’m spending a lot of time on TH-cam now (watching your vids), and a lot less time with my family. I’m sure wifey isn’t thrilled. Lol.
LOL!! You never know, she might be interested in it as well :)
You just saved my life …my mechanic can’t even understand the names of these suspension parts 😢
Yikes! Might want to find another mechanic.
Great guy ! Great overview!! Thanks a lot!
Glad to hear you found the overview helpful :)
Exceptional video
Glad you enjoyed it
Very nice. Thanks for sharing. Really itching to go to the dealership.
You're gonna love it.
Great video! I can’t wait to trade in my Rubi JK for the JL
You're gonna love it!
That was an Awesome Overview! Thank You!
Glad to hear it was informative for you.
Seam sealer.
Please make a video on how to properly torque and angle. Example lower control arm calls for 140 nm than 140 degrees
Thanks for the great video
You bet, glad you found it informative.
Great vid. Can't wait to see you're going to do to JET Li (any hints on your plan?). Love your JK. Counting down the days when my current lease is up so I can build up my own JL.
Thank you. We honestly don't know what we're going to do as of yet. 37's are in his future but how to get him there is the question mark.
It would be interesting if you compared the JLU 3.6 to the JLU 392 updgrades.
Awesome , very informative. Thanks.
So glad to hear it :)
Well done. Thank you. I learned alot.
Thank you, glad to hear it :)
We just got ours two days ago and we absolutely love it! Such an upgrade over the JK
There’s a ton of room where the evap canister was, that would make an excellent place to mount a drinking water tank.
Where the EVAP was is also a massive rock target and one that got hit all the time and to the point of damage. I'm very glad that Jeep moved it for that reason. But, if you don't rock crawl, yes, I could see that as being a good location for a tank.
@@wayalife hood to know! yeah I would set it up for long term touring/ overlanding, add a skid plate, water fill on the outside with a filter/ purifier and a 12v pump in the back with a tap.
Great video!!
Thank you :)
Thanks for video!
Could you help to choose please?
What is better: adjustable control arms or control arms brackets or 3-link long arm kit (diy kit)? These kits have approximately similar prices.
Using vehicle everyday and offroad on weekends.
Jeep Wrangler JK Unlimited Rubicon 2015.
Lift 3.5 inches.
The main goal to put 37 inches tires and make Jeep suspension is very reliable. Few times per year we go to the mountains for a couple days. There is no any service or welding or even electricity. So suspension must be very reliable to not to way some parts in the mountain:)
Based on what I'm hearing from you, a 3-link is NOT what I would recommend. Things break and with a standard 4-link setup, if you break a control arm, you can still drive off the trail with the remaining 3. You cannot do this with a 3-link setup. Drop brackets are typically cheaper to install and they will help to correct suspension geometry and that will give you a better ride. However, installing them will effectively lower a point closer to the rocks that you just paid good money to raise. Adjustable control arms are what I personally would recommend but depending on how much lift you actually get from your kit, your geometry will be off a bit and you may feel this. Also, it will cost more but it will be the most reliable.
@@wayalife Thank You very much for answer!
Very good. Dada.
Love the vids! I've been a supporter for a long time now and i personally own a 2011 Jk Rubicon 2 door with a 4" lift and 37" tires. When do you plan on modifying the new JL? Also would you guys be offroading with any 2 doors this year? I haven't seen that many in your videos.
Thanks, we're glad that you like the video. We've already got parts in to build up our JL but are trying to get as much seat time stock as possible first. More videos to come on that :)
Regarding 2-doors, it's not like we don't allow them to come. Certainly, we've owned one in the past. It's just that most of the people we know just don't have one.
Wayalife understandable. Thank you for your time to respond I love your content you guys produce!
Great videos! What lift do you use to work on your rig? Are you happy with it?
Thanks!
Looks like Jeep has done a good job, Now!! like the 2018 JL does the JK have all the same new features? Thanks
any videos covering "death wobble" ?
As always, great video and tutorial. I just purchased my first Jeep (JLU Rubi) and this is the first time I’ve seen the undercarriage. Looks beefy for sure. I’m doing the Mopar 2” with 35’s, so are there any components you would recommend replacing to ensure longevity and performance after seeing the undercarriage?
"replacing"? Not necessarily. the factory components are pretty good as is.
You have a lift in your garage. So cool.... The improvements you highlighted are impressive. How has your gas mileage been so far?
Well, we're still running on the original tank of gas that we got from the dealership. We have been doing a lot of testing and did some off-roading but in spite of it, we're still averaging about 16 MPG.
And the front shocks are now a bolt through eye design on the top as well as the bottom. Much less of a pain in the ass.
Yup, the rear shocks now use through bolts too. This as oppose to bar pins.
Hey Man, nice videos! I was thinking about getting one, but now I’m convinced! Do you plan on putting a lift kit and 35in or great tires on it? Bc that’s what I’d like to do when I buy mine
Thanks! We're actually going to be running a set of 37's but 35's would be a great size for the JL.
Wayalife would you say with a 2” lift or on stock? I’ve heard people say that it’s possible to run 35”s on stock?
You can run 35's stock but if you wheel your Jeep, your tires will rub the fenders at a full flex.
very nice. sounds like they did good
Yes, it does look like they did okay :)
Wow they really beefed it up!
It's about time :)
Thank you for such an in-depth and very informative review. I’m not sure if you’re aware of how much folks like me rely and trust you’re knowledge and insight, I don’t make a move until I find info from you’re content. Now I understand the comparisons you make are jl rubicon to jk rubicon but wouldn’t a more apples to apples be JL rubicon to JK rubicon recon ?
Not necessarily. The only differences between the JK Rubicon and Recon is the front axle and just barely at that.
only the JL Rubicon model have Front Axle Disconnect ? or its also available on the sport and Sahara ?
They all have it now. Well, all except the new 392 model.
I am waiting to see the new 4 cylinder JL Rubicon before I make a decision to buy. When should it arrive at the dealerships?
They should be hitting the assembly line next month or so. Maybe a month out from then.
I’d like you to do a comparison view underneath of the 3.0 vs. the 2.0 and what if any difference there is between the two suspension wise. Also, I haven’t seen and reviews of the 2.0 vs the 3.0 in quite some time. The 2.0 has been around for two years now and needs a more in-depth review. Thank you for all your great videos.
I would love to. Only problem is, the 3.0L isn't out yet and we don't have a 2.0L - Sorry.
Wayalife Sorry for typo, I meant the 3.6. There were some early comparisons but nothing recently. Thank you.
@@josephremenar3117 Suspension wise, there's no difference. Performance wise, I find that the Rubicon with 4.10 gears is an awesome setup. Anything less than that and I'd still prefer a 3.6L. On ledge climbs like what you find in Moab, I still prefer the 3.6L as well. Otherwise, the 2.0L with 4.10 gears and stock tires is like driving a bat out of hell.
Why on a 2018 model do we still see jeep wranglers with surface Rust on underbody suspension components? Really keen to see the JL in Australia, nearly bought a 2017 JK, but when getting underneath then, everywhere I looked on a display model, nothing but surface rust on casted components, and dealer said he could do a full underbody spray on systems at my cost of $1500, clearly you can imagine my response!! “I’ll let you know”..
I recently bought a 2019 JLUR, and the window sticker indicates that it came with '3rd Generation Dana 44 HD Wide' front & rear axles, yet your video says the Rubicon comes with M210 axles on the front and M220 axles on the rear. Are the ones you mention the same as those the window sticker lists?
They are the same. What I'm referring to is just the technical names of them.
Great video! Do some Jeep owners put line-x coating underneath the Jeep? Will you put line-x as an undercoat to this jl? Would you recommend it?
We have never undercoated any of our Jeeps and won't be doing it on our JL.
Just noticed the JL’s headlights when you pulled into the garage. Are those halos? Are they stock lights or aftermarket?
The halos are stock IF you get your JL with the LED group.
I saw on redlineautoshow they put a mopar 2" lift with 37's with wheels that had -12 offset. Will the Sahara driveline and axle's/gear ratio handle 37's or is it doomed? You think your stock Rubi can take 37's with the high line fenders and remain reliable?
Hard to say at this point and time but we'll be putting ours to the test.
Wery nice ! But there is one big question ? What will happen if im going evry day offroud and get too much repair pats ??? Taht will cost of hell too much money.... why they build evry time more complicated models ?
Could you do a comparison between parts on the Sport vs. Rubicon JL? Thanks in advance!
I really wish I could but we only have a Rubicon to work with. The Sport does have axles that are about 1.5" narrower and the front axle is now an M186 and the rear is an M200. No sway bar disconnect motor and the low range isn't as low. More info on all this can be found on www.JLWRANGLER.com
You should really have rubber pads on the hoist arm points that contact the vehicle.
can't wait to buy one in 5 years lol
Man its so shiny under there! Enjoy it while it lasts haha
LOL!! It's not so shiny anymore :)
gah why do they insist on routing the transmission lines under the bell housing! that is exactly why i got one of those Rubicon express transmission skide plates on my jku to protect those cooler lines from all the salt up north. hopefully the design one for the jl!
Also funny how the drive shafts are now painted on the jl!
There are several companies working on a skid for this.
The front cover over the swaybar link is also metal now! Should have been from the start. Are the bumpers all metal as well?
Only if you order your Rubicon with the steel bumper group. Otherwise, they come plastic standard.
Great video ! , I’m familiar with the terminology of Dana 44 but never heard 220 , what’s the difference ?
They're just new Dana axles. The 210 front and 220 rear numbers refer to the ring gear size in millimeters.
Hello boss, I recently bought Jeep JL 2018, 78000 kms on it. It has 33’ tires, 2.5 inch skyjack lift kit. It makes clunk sound on slow big bumps mostly on the turns.My Drag link was having little play I have change it but still it makes the same sound. Technicians had taken a look on it but he was unable to find any thing.there’s nothing loose even. What can u suggest.
Thnks
Have you checked your sway bar links and shocks to make sure the bolts are tight on them?
「あなたのコンテンツはとても感動的です」、
what are your guesses for the reliability of a JL? i plan to get a 2 door sport for beach cruising here in florida
Hard to say for sure with any new model but if reliability is a concern, I would recommend getting the 3.6L motor as it has been tried and tested since 2012.
Show us the suspension on a regular sport I see the links are bigger but what about the joints
Sorry, we can only show what we have on our Rubicon. The control arm joints appear to be clevite bushings just like the JK. The tie-rod, drag link and track bar bushings look like they might be the same too or at least in terms of size.
What would you change underneath .? Look like you need a little bit more protection underneath the Jeep
If I could change anything, I would try to protect the transmission cooler lines better and if possible, find a way to position the steering stabilizer above the front axle.
What are your thoughts on the new spring isolators?
I do like how they are integrated with the coils. This should help them to always stay properly indexed even if the coils were to shift or rotate at a full droop.
What's the axle tube wall thickness on the Rubicon vs. The regular jl
There no info. On how the sway bar mechanism actually works. We want to see that.
The sway bar motor has been around for a very long time and there's definitely information out there about how it works. It's just a motor that separates a gear that ties the two ends of the sway bar.
those heavy-duty looking stuff turned out to be very thin, there is a youtube video about someone cutting it
Awesome thanks for..watch
I need aome help with my jeep i want to change the suspension and the under body ? Any ideas where should i start
Sure I do. Sign up www.wayalife.com/ and there will be plenty of people who can help out, including me :)
What I would like to know will any of the jl parts interchange with the jk ?
There might be a few things like the front bumper but it isn't a good fit. The JL is a longer, wider and bigger vehicle all the way around.
Ya I read where it was 1 to 2 or so inches all the way around I still wouldn't give the 3 to 5000.00 more dollars over my jk what I did see is the front bumper is way larger than the jk
Hey Eddie, is the rear 220 still a 3" axle tube?
Yes.
The trac bar is bigger but isn't it hollow now?
A bigger tube can be A LOT stronger than smaller solid bar.
That makes a lot of sense. Also, every time you reply to one of my comments I fan-girl and tell it to all of my friends. Last time was on one of the Calamity Jane videos: I said something like you had a majestic voice that was like the Morgan Freeman of Jeep videos. Or something like that. Can't wait for the upcoming build videos for Jet-Li!
Very well presented and wished it was equipped with a diesel. Thank you.
Thanks. Diesel would be nice but they won't be available until the end of the year at the soonest and they will push the price of a JL close to $60k
On which trim: a two or four door, soft or hard top. Thanks
Last I heard, the diesel will ONLY be available on a 4-door. The difference in cost between a soft top and hard top is only about $1200
@ 4:49 is the top shock bolt loose or does it have a spacer on it?
The new upper shock mounts now use through bolts instead of a stud up front or bar pin in the rear.
Is the new track bar adjustable?
No. There is no need for it to be from the factory.
Do you believe that the FAD will be problematic?
Hard to say for sure at this point and time. The more plumbing you have, the easier it is to stop up the drain or in this case, the more wiring you have going, the more likely something can go wrong.
That's a lot of beefing up. How much does the weight suffer?
The JL has a lot of new aluminum parts and is actually lighter than the JK.
lighter by a couple hundred pounds is what I saw
Question should be, will it death wobble after 25000 miles
Anyway to put an Electronic Sway bar Disconnect on JL Sport S?
Yup. If one were so inclined, I can't see why you couldn't. Guys have been doing it for quite some time on the JK.
Any changes on the exhaust systems?
The exhaust system is a bit different for sure. Super quite.
Really Chrysler? Just had to add CAD didn't you?
Otherwise nice to see some of the improvements but, I can't believe how tiny that oil pan is.
At least it uses an electric motor as opposed to a vacuum like the old CAD. What I can tell you is that the engineers fought to keep it off.
The oil pan is not only tiny but it sits higher up as well. This is a good thing :)
I've had experiences with the vacuum CAD on my old ZR2 Blazer. Nightmare of a system. I've noticed the electrical (motor) driven CAD systems seem to be far more reliable. Even with that, I'd say someone will come up with a 1 piece shaft upgrade (Unless Chrysler has some wonky electronic stuff going on).
Dynatrac already has a 1 piece shaft coming but the FAD is connected to the transfer case electronically. They're working on a way to fool the computer into thinking it's still there.

can new axles hold up 37" Tire or only 35" tire
Not sure but we intend to test them out with 37's. Time will tell if they're up to the task :)
Wayalife
can't wait to see that video
I can’t wait to see that too, as I’m hoping they’ll hold up!
Can I put 37s on a jl Rubicon with no lift?
Not without rubbing.
so... mopar 2" lift time? 37s?
37's are on order but we're not sure what lift to run as of yet.
Yess I can't wait
I'm leaning towards the Mopar 2" on my 17 jk with 35s so I don't have to regear at the moment.
How much for the 2inch lift?
chris pomplun last time I looked it was close to 1k, the reviews for the Mopar kit say that the set up of the 2inch lift allows it to have the same travel as a 4inch lift.
Wonder when people will start swapping JL Rubi axles into JKs lol
Ryan's Jeep Garage yeah when hell freezes over, Lmao. Who in their right mind wants a FAD, its the YJ all over again.
Matt Clark nothing wrong with FAD. You gotta remember the YJ came out in the 80s. We’re talking 1980s tech verses modern tech. It really isn’t as big of a deal as people make it out to be
Ryan's Jeep Garage The system itself is probably okay as it is, but i know a lot of guys that run 37s on stock JK axles with regears, trusses, gussets, and cromo shafts. I feel like if guys try running these new JL axles like that there will be problems down the road that the 1 piece JK shafts didnt have.
Firestarter I guess what im trying to say is instead of putting ANOTHER electronic system in a water and salt sensitive area, why couldnt they just do a full float system. Most aftermarket axles run them or make a kit for it anyway, so why the weak spot. At least this way if you want to have your axle locked all the time just leave the hubs locked, and that way Jeep still gets their gas milage down for the EPA.
if they improved everything that much why lots of people have steering issue and dw :(
