The Rock Ballerina: Jeep Wrangler JL on 40s and STOCK AXLES (2 years later)| Inside Line

[@JeffHallPhotography]

2018 JLU, 40" Mickey Thompson on stock axles and still running strong after 85,000 miles. Been on the Rubicon, Fordyce, Moab, Moon Rocks and so many more!

[@DimplesChild401]

What did you regear to, or did you order yours factory with the higher gear ratio?

[@JeffHallPhotography]

@@DimplesChild401 still on stock gears

[@turboleggy]

Sick. No upgrades to the axles?

[@ghernandez6457]

This makes me feel safer about running 38s on my JLUR on 4.10s 😂😂

[@spencemad_4x427]

I like how this setup has forced him to be more methodical when wheeling

[@Mplonk13]

I have 26k miles on my 2020 Gladiator with 40's and stock axles. The axles have held up with no issues. Same fuel economy between 14-15 mpg depending on driving situations. I figure ill have to upgrade the axle shafts and ball joint eventually. But im in the same situation, Figure ill run it until i have a break and then order the needed upgrades to fix it.

[@donaldhalvorsen4135]

I get 14-15 in my ram 5500, and I weigh in at 18k, you must have a gasser

[@TonyGilliam]

5k miles on my Mojave on 40’s. Need gears, but wouldn’t change it for anything!

[@immelting9834]

Wj on 38's here and JL axles. Lighter vehicle than a Glad . Ive broken 3 axle shafts , 4 ball joints and put a nice smiley face by bending the housing. All within 11k miles . However, I'm in Tennessee so a dramatically different terrain . Going 14 bolt rear ( shaved) and a D60 front next month. Mpg with the JL axles was 14 city and 18 hwy with 4.56 gears.

[@jeffreid3341]

@@immelting9834 what's your driving style. Just asking to help me decide on my build. Thanks

[@nicklange6994]

Curious how this is going. I have 40’s now on stock axles. Wondering if you’ve had to buy new ones. And have you wheeled hard with it?

[@stormw777]

I got 37s on my 2018 2.0 turbo which has 38000 miles of offloading and it has had zero problems.

[@TheHitSquadOffroad]

I've been running 39x13.5r17 on my JT for about 4 months. My wheel setup is about 135lb per tire/wheel. I haven't done any internal upgrades in the axles besides a regear to 5.38s. I take it pretty easy on the trails especially when rock crawling. I'm not skinny pedaling through obstacles or over rocks. I'll upgrade the internals or overall axles in the future, but so far so good.

[@Jeeps1]

SOOOOOOOOOOO stock 44 housings but nothing else stock????? that's what the title should say

[@DrivingLine]

The goal was to highlight the items he has upgraded to make the axles survive over the past two years. Hopefully, others that are trying to do the same can benefit from his experience.

[@DUNEATV]

Great video again by Ali! Great to know my 21 Rubicon is a pretty tough rig! 💪🏻

[@wibornz]

I ran forties for a little bit. I Jeep travel a lot and pull a small camper. With 37s, I get between 12.5 and 16 mpg towing the camper. With the 40s, the best I could get pulling the camper was 8 mpg. That means that I did not have sufficient range when traveling out west. So back to the 37s I went.

[@reptilewizz]

Did you account for the mileage discrepancy between the bigger tire and rotations per mile.

[@wibornz]

@@reptilewizz I did adjust the Jeep computer for the tire size with a Tazer.

[@brianhayes7108]

I have 40s on stock 44s. Horseshoed the front axle at the dunes (also bent the lower control arm drivers side frame mount. Fun times.

[@reptilewizz]

Did you get air? I figure the dunes would be easyer on everything?

[@nickburns5571]

Blew up the rear on my 44 after two years. Came down hard on the rear driveshaft trying to get up a ledge. Just threw in some new gears and still need to get the driveshaft straightened. I will probably go another 2 years before building tons.

[@Joes-Adventures71]

So not stock axels?

[@spencemad_4x427]

Yeah that’s what I was thinking

[@kp_patillo]

Ok so how are these axles stock. He says in the beginning around 1min in that he went with upgraded Dana's and then Dynatrac's in. Cast Iron knuckles as well. Wouldn't this be modified and not stock?

[@Ali_Mansour_Editor]

He’s referring to ball joints when he mentions Dana and Dynatrac. He had the aftermarket Dana ones that failed and he upgraded to the Dynatrac ball joints after those. These are still stock housing, with stock lockers and stock unit bearings. This was my follow up video. He was still on stock ball joints, knuckles, and axleshafts when I shot it originally. While he does have some quality aftermarket upgrades, these axles are way more on the stock side versus an aftermarket housing.

[@GentlemanJim]

And the actual axles are RCV. Nothing stock about upgrading everything in and around the axles…..

[@GentlemanJim]

@@Ali_Mansour_Editor RCV axles shafts are not stock.

"If I wanted Fuel Mileage, I'd a gotten a Prius" Thank YOU! Yes! It's about the Journey and Fun. I have a 1990 M923A2 6x6 that gets 8mpg and I smile every step of the way :)

[@lol123321123321]

The hub bearing bolts and or studs simply retain the bearing to the knuckle. They aren't actually holding the load of the vehicle in static form, the knuckle itself is. Yes the super duty hub IS much larger but the hub stud comparison is almost irrelevant. That's not a failure point to begin with. I've changed hundreds of worn out super duty hubs and a few jeep hubs. Failures never revolved around weak hub bolts lol. Ball joint size, knuckle separation, and axle u joints is the main difference. Other than the obvious the D60 housing is massive

[@cd2875]

BULLSHIT...NOT stock axles. Stock HOUSING!!!! CLICKBAIT.

[@persicon_jl]

Ali Jon, great interview agha.

[@KaptenInsano]

I have 4.88s and thinking on 40s, hoping it will be good enough. I already have upgraded axles in the works. Rcvs up front and chromoly in the rear.

[@DimplesChild401]

4.88 is definitely the sweet spot.

[@ghernandez6457]

Did you get 40s yet? I have 4.88s on 38s and I think it goes through gears too fast, I've hit 8th gear by 50mph I think 40s should be good enough. Same rcvs up front and chromolies in the rear. 3.6 2018 JLUR.

[@EPYCMX]

Stock upgraded axles... Lol

[@jaycrane761]

He’s says he’s changed and up graded axels So how’s it rolling on stock?

[@DrivingLine]

The Jeep still has the stock Rubicon axles, they have just been upgraded with a few components. Over the past two years, he's upgraded the axleshafts, ball joints, gears, and knuckles.

I didn't see hydro steer....how are you turning 40s without it? I'm looking at a very similar setup

[@ghernandez6457]

I run an Apex power steering boost kit on mine. 40s on trussed d44 rcvd. 4low 10psi I am able to turn them bitches fairly effortlessly, not PSC easy but doable. Fully locked 4low it's 50/50 sometimes youll be able to steer sometimes you will not. Still ten times better than stock steering.

Great video brother. I want to go bigger with tires and this shows with care it can be done . Stay safe!

[@Ali_Mansour_Editor]

Thanks Chris! Hope you are doing well my friend.

[@stephenluebbers5282]

2018 jl with stock axles and 37" toyo mt. I have broken a rear axle shaft, rear locker, bent a chromo rear shaft, front wheel bearing, and ball joints have all failed in 35,000 miles. Imo anything over 35" when wheeling and you are on borrowed time.

[@jiovannypreciado3821]

Toyo Mt’s are bad ass but they are extremely heavy. Your 37 inch Toyo weighs more than my 40. Weight of the tire is a big factor on the health of an axle. If you want to try 37s again go with a lighter tire.

[@stephenluebbers5282]

@@jiovannypreciado3821 yeah I ditched the beadlocks and went with 37” maxis tires to cut about 50# a corner. It has been better since then.

[@cd2875]

Stop driving like a 15 year old. This is why you break shit. Ive had My JLUR in Moab, and I live in the east crawling on big slippery rocks since I bought it. 37's and stock axles. If you pick good lines and not try to bounce over everything, the D44's are superb axles. But...internet yahoos know everything. Best thing to happen for off road upgrade sales.

[@stephenluebbers5282]

The only time i broke driving ignorant was in the hot tub in Moab. There was 2' of water in it with a layer of oil and grease. The locker and axle broke on a small bump at a local park. @@cd2875

[@mazencattan]

Are the tires rubbing when flexing?

[@matthewharris3081]

14mpg? not bad that's about what a stock 4xe gets when it runs out of batteries.

[@Intentsrig]

How long did he run the aluminum knuckles? Mine never broke but the upper ball joint was wallowing out on 37's after about 3.5-4ish years. And can't believe he didn't truss it. Seems Speed is definitely what kills the fad part of the housing (snapping in half). Well, speed and smacking something large in the path of the tire or catching some air time.

[@DrivingLine]

I believe he had the stock aluminum knuckles on for less than a year.

[@daviddepue6499]

The only thing left "stock" are the housings lol.

[@bendmacmanufacturing2744]

I owned my 4xe since May guys and I love it 2880 miles no issue's no mods yet properly will limit mods due to it being a 36 mo lease !!!

[@jimsather6892]

Were the cast knuckles covered by a TSB like the steering box? If so, do you have the TSB #?

[@DrivingLine]

No. These were purchased separately.

[@jcs5449]

Any one running 35s or bigger on a stock sport? And if you are how is it holding up?🤔

[@RubyRecon]

I have 35s with 2.5in lift on my 2021 sport s 2.0L and it’s held up great. I don’t do serious rock crawling but for my everyday commuter and weekend mild off-roader it’s been a blast. Definitely hit a few bumps and minor jumps I should t have but knock on wood haven’t broken anything.😅 I know he said we don’t get these vehicles for fuel efficiency but since I commute in mine it’s definitely been a consideration on why I haven’t gone to 37’s yet. Been averaging 18-19 mixed city/hwy.

[@rmat9023]

but why tho, 40s and no lift = rub and poor flex.

[@laloolhouvum1634]

Spare tyre delete makes jeep looks like not a jeep. I, would never delete my spare tyre.
