Gear break in, what to expect
Вставка
- Опубліковано 7 тра 2020
- Bigger tires usually mean its time to regear your vehicle. Some will tell you that you don't NEED to re-gear, but you really should. Being properly geared helps keep everything happier in your Jeep. Transmission, engine, and other driveline components. Being improperly geared puts a lot more strain on these parts.
I went with Revolution Gear and Axle gears, 5.13. In this video I talk about the break in process for the gears as IT IS IMPORTANT.
Always double check with your manufacture on the correct break in process. I go over RGA recommended process.

I am breaking in the 4.88s I just installed in my TJ with 35s NOT on stock axles, like just drove it first cycle tonight. Your not only breaking in the gears but the bearings are breaking in too. Also, biggest reason you cycle and cool is to keep the gear oil from getting destroyed from overheating during break in. Once the gears and bearings break in they run cooler.
Great video! Just getting ready to go thru this process myself! Was searching this topic and just stumbled across your channel. Good stuff! I’ll be showcasing my new mods soon and will touch on this subject as well. Subscribed! ❤️🐞
Awesome! Glad to hear it! 🙌🙌
Did my break in slightly different, but similar. Eneded up with a nice pattern like yours
Wow 👏 sounds like a huge process besides the installation
I’ll do tht video some day 😂😂 it’s a lot of... everything 😂
Another well done video! Thanks Mo.
Absolutely! Appreciate you watching Tim! 🙌🙌🙌
Lol, an excuse/break something for the next axle🤣
Awesome video!! Makes sense and will get with the guy that is installing my gears to see what the break-in for Yukon gears is like.
Sometimes ur just looking to upgrade 😂🤷♂️ regardless of brands... expect something very similar to what I showed in the video. 😂
Thanks good info, a lot of gear change videos out there and I don't think any talked about break in. Maybe they assume we know that already, but if they assume that, they should assume we know to change gears. That's why channnels like your's are getting so popular, down to earth, entertaining, good info, and not just in it to make a buck or get sponsorship. You rock! Maybe you should go bigger tires 42s, to see how stock axles hold up. But wait until you have the funds for new axles of corse. Love ya, Oh and tell Misty we need more jokes.
Hahahaha appreciate the awesome feedback.. I feel I missed a few key points thou... lapping and break in with a fad 😬😬😬😬
Iv seen some people tell others.. breaking in is not important... I 100% disagree... u will also see a large difference in methods of break in from person to person also... 😬
For all of you E-locker owners out there you will want to put very strong magnets on the diff dover where the fluid is spinning around inside. The E-lockers use magnets, and the metal fines from break in will get inside the locker magnet. External magnets catches most of these fines, so your locker will live a long life.
Great Video Thanks for making it
Nah bro... thanks for watching it 😉😂🙌
I agree with ya on paying someone else to do your gears. I’ll do almost anything else maintenance or upgrade wise but it’s nice to be able to have a shop to fall back on if anything happens with the gears after they’re properly broken in.
Gears are doable,.. but tedious if u don’t have all the special tools. Rip it all out... put it all in... test... wrong repeat... never scared of a task....
Great video lots of important information
Glad you enjoyed brother.
Great video man! Not a lot of people talk about the break in process.
No.. not really.. super important step thou... I’ll do a how to regear video on the jl... just wasn’t quiet ready 😂
JL LIFE OFFROAD haha i dont blame you i agree with what you said not something i want to tackle on my daily don’t need to rush installing a gear set
I didn’t think a rough install based on feel would of in best take on it... I need tools lol
JL LIFE OFFROAD 😂🤣 the ever growing issue do i buy jeep parts or tools
Lol... yea.... tools have been my focus lately 😬
Another great video, thank you. Have had gears done only on mustang's and there was no break in period. But what your saying make sense. Enjoy the new mod.
With offroading... we put a lot of strain on parts... R&p is the last thing I wanna break because things weren’t quite right... I know someone who regeared their jeep... decided break in was not needed.. drove and towed right away... lost a handful of teeth during his short period of having em..
Another one of those .. do U HAVE to? No.. SHOULD you? ABSOLUTELY
@@JLLIFEOFFROAD when I do gears I will definitely follow these directions if the gears I choose dont have a beak in recommendation
Hector Serrano they should be close to em regardless of brand.. but definitely follow manufacturers recommendations! 🙌
Bruh, they all have a break in procedure! All ring/opinions on any vehicle ever. Sounds like you were missing a page or buying junk. But make zero mistake....there is no such thing as a gear set that doesnt need broken in
Great video! Regearing makes a big difference. The break in process is important.
Very! How much time effort and money regearing is... I tel everyone to just do it right
awesome video and that diff cover will provide extra fluid capacitity and cooling due to more fluid
We went 4.88 and BREAK IN SUCKSSS, then we had to do it all over again because our rear backlash was too loose... bad installs suck! Thanks for sharing the experience 👍
It’s hard finding good quality shops... which is one of the reasons I prefer doing my own work... regearing... tire mounting/ balancing and proper alignments are the only thing Iv paid someone to do to my jeep... however... regearing will not be in tht list next time.
Thanks great video! I live in a small town no 4x4 shops I have to drive 200 miles have my jeep regeared. Looks like It will be easier to spend a few extra days in the city doing the break in first, rather than heading straight home.
After the initial 3 cycle period... u can go much faster... just be sure ur still pulling over to allow cool down.
Thanks for the vid. Hoping to do my 5.13s soon-ish. I was holding out to install my diff covers for my regear but gave up and did them last weekend. I'm going out of town to do my re-gear. Should make driving home annoying. I figure if I take back roads and stop every 20-30 I'll be fine.
Yea.. long as ur taking breaks to cool down... having the thinner diff plates will help it cool down faster... just something to keep in mind. 5.13 is a good size and easy for me to recommend! 🙌🙌
Love the video...With 5.13 gears in the JL rubicon d44's, do you think the weak point becomes the ring and pinion considering the 5.13 pinion is noticeably smaller? Or are axle shafts/u-joints still more likely to break first? I've read rcv's/chromoly shafts further shift the weak point to the ring and pinion. Thoughts?
Yes... it will... but my opinion ur less likely to break if ur able to keep the rpm’s lower... of course nothing is fools proof. Iv seen someone on 35s and 4.10s put his tire in a bad line and absolutely Grenaded his transfer case and snapped is axle shaft in half
I'm surprised the shop where you got the gears installed didn't follow up on a visual inspection of the gears and changed the fluid. I do re-gears exclusively on jeeps in OKC for 250.00 an axle non-rubicon 275.00 per axle for rubicon with a follow up to check the break in was done correctly also measure backlash just in case. To ensure quality workmanship
Drove it around for a hundy! Did another gear oil change,and hit the rocks... just like the gears that came in the jeep.
No MARK! Thts not how to do this! 😂😂😂
Whats up JL life yo just got the same gears and stoked.
I have a manual with centerforce clutch it should be a beast when new gears are installed. Would love to wheel with you.
Which state u in?
Gears are life changing offroad!
If we still have a FAD, how do we proceed for breaking in the front diff?
Throw it into 4hi when going straight every once in a while?
Bingo
Yup I’m at this point now so thanks for this video a few years later! Lol!
Just doing my civic duty 😂 🙌
@@JLLIFEOFFROAD greatly appreciated! Just followed u on insta too I’ll tag ya when I start this break in process! Should be out the shop tomorrow !
Where you at bro? I’m moving to Cruces this summer and my truck will be built up soon for wheelin!
Albuquerque my man 😎
another great video and i was also wondering if you would post where u got the diff covers from along with your rear bumper
Added the plates to the description
Here is the bumper link

@@JLLIFEOFFROAD I have that same CavFab bumper slightly used for half price is someone is interested.
Just regeared my JK 3.21s to 4.88 , went to Vegas and the 35s with 3.21s felt like a slug, I was stuck between 4.56 or 4.88 went with 4.88 but now I feel like I should have went with 4.56 I don’t like the high rpms the 488s has I go wheeling time to time not a whole lot which I’ve been told 488s are a better option for serious trail heads, any advice? I might just give the 488s some time to break in and see how it does on long hauls
The Jl... has an 8 speed transmission which makes a huge difference. U won’t experience any difference the longer u wear in ur gears.
Just put 37" tires on and problem solved!
With the front axle disconnect, the front pinion won't be turned by the ring gear as the spider gears will just be turning in two-wheel drive I would assume. If we are still running the stock FAD, I wonder if we have to put it in 4 high and do the break-in OFF asphalt or if there is a way to make the FAD connect in two-wheel for the break-in?
U need to throw in in 4wd during straights on road, back to 2wd on turns.
I’m so glad you asked that! I was wondering the same thing and haven’t found any info on it but common sense tells me to throw it in 4 Hi on dirt roads to break em in.
@@JLLIFEOFFROAD I’ve been reading all your responses to people’s questions and you’ve helped me out a lot. I also just re-geared my JT to 5.13s. So far I’m loving it. You’ve earned a follow from me! Keep up the good work!
Would it be a good idea to mark some of the teeth to monitor the wear the next time you open the cover?
Can you advise on how much the install would cost? This would be something that I would probably pay someone to do also is why I'm axin.
U will know if the teeth are not connecting right... the rubbing wear... will not be centered...
Cost... is not cheap.. U can expect to spend anywhere from $1200-$1800 for labor... of course the parts cost another $1000ish.... if u want lockers.. perfect time to have em done also...
We plan on buying some 44s for mistys jeep... I’ll be doing tht gear how to when we cross tht bridge...
Typically good gears won’t be cheap especially if you decide to go bigger than stock you also have to match spline count unless you plan to upgrade the axels, most units will also require a speed sensor update or they will throw tcs lights on the dash… most installs cost between 2800 parts and labor but they can exceed the 4000 limit depending on your preference in parts
Great video I had to come back to watch it again before I go get my regear done on my 16 jku. For 3.6 auto 5 speed running 33s (285 75r16) would 4.88s be too much? I'm in the PNW. Charts say I would be around 2700 rpm at 70mph. Doesn't sound horrible. Not going 35s anytime soon with the D30 front. Any input appreciated. BOO 3.21s!!!
Personally... I think 4.88 on a 5speed and 33s is way to much... for tht tire size I’d recommend 4.10 or 4.88 depending if ur looking for on road or off road performance
@@JLLIFEOFFROAD Thank you for your quick response :) Love your vids! If you keep crankin them out Ill keep Thumbs Up-ing :)
I like it 😎
Great video, My question is in the break in period do you have to use 4 wheel high?
When your going straight, keep it in 4x4. When you are making a turn, quickly shift it back into 2 wheel drive. Putting the front under ‘load’ is only gonna break in the front more properly.
Of course if you have the FAD connected, you 100% have to have it in 4x4.
So to break in the front diff do you have to do all that in 4hi? I thought with the FAD the front doesn't spin in 2hi.
Yea... I have done the fad Delete axle well over a year ago and hadn’t really thought about the fad...
U WILL need to be in 4wd in order to break the front gears in if u are running the fad still.. I’d recommend throwing it into 4wd on straights... shifting back to 2wd when u have a turn coming up...
Do you drive it in 2h or 4h because why do we only break in the rear and not the front
So what about the front diffs? They are not engage unless in 4x4. So for the front diff do you drive 500 miles while in 4x4?
So deleted my fad ... so it’s always turning.. I recommend throwing it in 4x4H when ever u can... putting it under ‘load’ will ensure the break in is proper..
Just got my new Eaton E locker and fresh rebuild rear end broke in. Took a few weeks for me
Tedious for aure
Great vid,,,Do new gears make a slight noise at first then go away after break in ?
It can.... what kind of noise are you hearing??
@@JLLIFEOFFROAD Just a slight humming at light throttle when coasting around 45 ,The gears had a excellent gear pattern
They can.... get through the break in... and re-examine
@@JLLIFEOFFROAD Thank you
Why we don't need to break-in stock diff? And no diff oil change rapidly? Done in the factory?
Thts because they stick them in a machine at the factory that breaks them in for people 🙌🙌
OK, just curious; you explained how gearing can effect torque for getting over obstacles, but what does it do to performance on the road? Doe sit improve/hurt gas mileage, increase/decrease acceleration, increase/decrease max cargo, etc.
Yea... be happy to answer y I neglected all tht... this video was not a ‘why you should regear’ video... more so focused on the break in... I touched on low end torque because a lot of videos mention it... but never really explain what it means... I’d be happy to make a video about why you should regear and touch on all those topics for ya...
@@JLLIFEOFFROAD It would be great appreciated. I am in the process of getting a Diesel Wrangler Willys and suspect the low end torque might be used to greater effect with (slightly) larger tires but want to understand what I'm getting as well as giving up if I regear when I (inevitably) lift and go bigger.
@@fretless05 If you are ordering a new wrangler there is a package now with 35" tires and 456 gears. All I can say is wow!
Did you replace both diff covers or just the rear?
Both front and rear
Don’t get me wrong nothing is bad about doing this but when we buy a brand new 60k plus vehicle do we spend time breaking in gears? I think breaking in New Years is great and all but probably just driving normally and changing the oil would be good enough.
I so need to do this
I STRONGLY advise it lol
When you are driving to break the gears in can you be in 2wd or do you have to be in 4wd?
It works better in 4wd… try to stay on straight roads… turning in 4wd isn’t pleasant
When you bought your jeep did you break that in 🤔? This is great info for the masses . I applaud the diff cover upgrades well worth the money.
No... but fun fact... the factory breaks the gears in with a fancy machine
Cheap insurance is my opinion on it... $100 vs potentially $1000 🤷♂️😂
I feel the pain on the cost. I have a Toyota FJ and revaluation gears as well. But Toyota's cost 2300.00 everything is more on Toyota. But I love the new gears
Thts strange.. I hear working on the Toyota 3rd member is worlds easier then Jeeps 😂
Being geared correctly is nice hahaha
Really the only special tools are a set of calipers for shim measuring($50 or less) a press ($150 at harbor freight) and a dial indicator($50). You can spend the big bucks and get a claim shell bearing puller for $300 or so but you can also just cut the bearings off. People will tell you its cheaper to take it to a shop..... but id rather spend up to $550 in tools that I get to keep and use than pay thousands on labor. I also don't trust shops either. Im very rarely happy with the work I've had other people do. If something goes wrong I'd rather it be on me, not someone else.
We must have esp I literally swapped my front diff yesterday, got ruff stuff front diff with my hydro assist tabs welded on it, I HATE GEAR OIL stinks so bad lol
I love ruffstuff! It’s BEEF! Hydro is likely a few yrs out for me still... eventually thou.
The dirtier it is.. the worse it smells
I just got my gears replaced here in Arizona . After the brake in process i went to a different shop for diff oil change and inspection and they found a lug nut washer inside my front differential plus the installation was incorrect . I called the installer and he will be giving my money back today.
Did U hear a clanking?? Thts horrible... stories like tht is why I HATE paying people to work on my jeep...
But glad to hear they are refunding u... hope they buy u the new parts to do it again correctly.
@@JLLIFEOFFROAD i texted you on FB
Give me a minute.. I’ll go look
If I traveled a few hours to get this done, could I just drive for 30 minutes and let it sit for an hour then rinse/repeat?
An hour is probably more then needed... for tht initial break in.. 20 min on... 20-30 min off would plenty
@@JLLIFEOFFROAD thank you
Thanks for getting back to me so fast! So use 4 wheel high for the entire 500 mile break in?
Is your fad still engaged?
@@JLLIFEOFFROAD
I been wanting to know this too. I still have my FAD(front axle disconnect) so I was wondering if I would have to engage in 4WD- 4HI for city driving to apply some load and properly break-in the front axle gears since the front driveshaft don't spin under normal use in 2WD. I don't see this getting mentioned on other videos regarding gears. They often forget the new JL/JT have the FAD. Any advice will be greatly appreciated!
What’s the difference of putting on new gears. And gears from factory regarding breaking them in they never say you got to break them on o new vehicle I’m just asking cause I don’t know the difference
No, the manufacturers have fancy machines that break the axles in before shipping the vehicle out
@@JLLIFEOFFROAD tks. I’m new to all this.
Awesome man! Yep break in sucks.
True true... so boring ...
Thanks for the info. I'm thinking of regearing as well. But now I have think about it more because my jeep is my daily driver. And have to get on the freeway to get to work. 😭 what to do.
What gear/ tire size u currently at?
Re gearing ain’t cheap... a lot of questions come up.. how long I planning on keeping the jeep.. how often do u drive it.. what kind of any off-roading are you planning on.. 😂 so many things it could easily be another video
@@JLLIFEOFFROAD I currently have 33' tire. As for gear not sure. It's a stock 2013 jk manual transmission. I want to get 37' tires.
Currently being on 33s... u should be fine. If u decide to get wild and put 37s on... u need to regear 😂
@@JLLIFEOFFROAD that's the thing I want 37' that is why I want to regear lol. All in due time I guess😂👍
Yes sir... all in good time 😂 Thts what I keep teling mysef
Hey with an fad and 4wheel off how do you break in front gears?
Put it into 4wd when ur going in straight lines. Shift out before making turns
I'm in the middle of having gears and a posi put in my truck.It has been a nightmare. I paid 1,200 for all the parts. Took it to a shop they charge me $800 to put it in, which was the cheapest that I could find in my area. I had to wait 2 weeks .went and picked the truck up and it was howling so bad I turned right back around and took it straight back to the shop. They then tried to blame it on the drive shaft.7 more weeks and I'm still waiting.
Sorry to hear that my friend… gears are one of those things that have to be exact… you have such small room for error. Gears are something I encourage people to go to a quality shop to do… that will stand behind their work…to avoid the headaches you are dealing with
Do you have to reprogram after the regear?
If you want your shift points at the right spot… yes
Did you have to flash the computer for 513’s?
Yes, if you want it to shift properly… that is a must. I used the tazer
Well the issue how you break in the front gears if you're still on stock front axle with FAD since the pinion is not spinning ?
Lmao.... u know... I didn’t even think about the fad 😬😂
GOTta have the gears turning.... means gonna need to be in 4wd high during break in. DAMMIT... Iv been fadless for the last year+ didn’t even think about it
@@JLLIFEOFFROAD that's gonna be an issue to be driving in 4wd on paved roads for days 🤣
Alternative is u prematurely break the r/p and start over. I’d say find a long straight stretch of road to do it on.
I mean deleting the fad has its benefits 🤷♂️
long straightaway with the jeep in 4 high, shouldn't be too big of an issue. but even with the FAD, doesn't that driver side tire still turn the ring? maybe not... i never thought about it.
@@JLLIFEOFFROAD yeah you just have to find a straight road and go back to 2wd on sharp turns , i got 1 piece rcv on my new front axle but for the people on stock axles gonna have to deal with it i guess lol
Do they break the gears in for the factory?
Actually, yes, they do. They have a machine that puts the gears under load and breaks them in before they ship em out
i'm honestly surprised you did 5.13, it seems like with the new 8 speed trans in the JL they play well at 4.88 with the 37 crowd. it's the happy medium (so it seems)
Having tht 8speed... 5.13s are great... Iv heard 4.88s also been working great for people... tht the rpm difference is just a few hundred.
I rather have more performance then onroad 😉
@@JLLIFEOFFROAD that does indeed make sense. Either one gets you into 2nd overdrive on the highway. It was so windy coming out from Colorado we had to keep our speeds down to 70 or less anyway.
Lol I mean... it’s close to
The sped limit lol
It would be better to explain that the expectation of the thickness of the flange on the cover is similar to the geo-shape of the cover itself. And the amount of fluid is dependent on the size of the cover as well, need to fill to the bottom of the tube (inner diameter) cause that's where the axle seal is located. (Want to be able to pull a shaft and not have fluid drain into the tube where potentially, you can scrape dirt back in when reinstalling shaft.)
Yes those are valid points... the things I always leave out when I don’t write out my ideas on videos 😬
These have been designed to hold two quarts of oil.. I spoke to the owner of cavfab about em...

It’s done during the factory process
Don't use yukon. Shit will break within a week
Sorry I'm a beginner, fad?
Front axle discount, it saves a little bit in gas and wear.
I’m assuming it’s still in there, so in tht case you absolutely need to be in 4x4 for the break in
You are actually braking in your bearings not gears. gears are a match set and are hardened 😎
Lmao.. I hear used diff oil makes excellent blinker fluid also 😂😂😂🙌
@@JLLIFEOFFROAD your bearings and races are the meager parts you are braking in the gears if setup right will show no ware in that time
See this is the bullshit I don't believe at all. You're telling me you have to baby new gears yet when you buy a new vehicle you don't have to worry about that. If you have to baby it then that means it's shit.
They have a machine at factory tht puts the gears under load during production and breaks them in before they even ship
What a bunch of bs
Why don’t you have to break in gears on a new car? If you go in reverse is it better for break in
