Also, with the idle-gear forces now symmetric and distributed over 3 gears instead of 1, and supported by the smooth circular ridges of the bevel gears instead of the points of the cross-axle holes, this should run a lot smoother under load, too.

The main problem that I have had with the older differential is that the axles would pull out of the small gears, and the gears would drop out and roll away.

This is an good differential. Thanks for reviewing

Just the fact I don't have to fiddle trying to keep the 5 12-tooth gears in place while adding the axles is big plus. The previous version was a nightmare for my fat sausage fingers.

I don't know why this hasn't been bigger news (that I haven't seen so many other people talking about this). Thank you for letting me know about this awesome new part.

Glad LEGO brought back the lock-ring compatibility with it, that was one of the biggest issues with the last design: no simple way to diff-lock! Now LEGO just needs to make the lock-ring more readily available.....

This also has the potential to have different sized ring gears in the future, either from Lego or designed as a custom part. Maybe we'll finally have a system that's compatible with both the bevel gears and spur gears without awkward spacing between the gears.

Thank god it's enclosed. I'm tired of the axle of the bevel gear getting pushed into the middle of the differential and locking it up!

Great run through! Thank you. I was looking at it earlier wondering what all the pros were. Really looking forward to seeing how this one is used

I was confused on how it was better. Now it’s clear with this video. Thanks a lot!

Great improvement, excellent review, thanks!

Thank you for the detailed explanations.

Yes! Finally a new design. This is wat more cooler than I expected.

VERY comprehensive and thorough review of what appears to be a critically important upgrade in LEGO Technic drivetrain components. Or, as Will Smith said in ID4, "I have GOT to get me one of THESE!" 😁😁😁

Thanks! this review was very helpful for me, I think I will be better off starting out messing with the last version

Great review, thanks.

perfect video also a good touch to history. thank you

Great review. Thanks for sharing.

I'm glad I no longer have to assemble the new differential every time!

In recent years, new LEGO parts have been a huge letdown such as the new train wheels, PU issues, etc. this thing is awesome! I can’t wait to get some!

this new brick looks cool!

They are available in the lego website now. $1.96 the housing, $ 2.24 the red gear, a total of $4.20, definitely their most expensive differential to date.

Why did LEGO use the big 4 port hub instead of the smaller 2 port one in this set? You can find it out here - kzfaq.info/get/bejne/rNdhgJeSrt-Xo4U.html

Oh those pieces are a new differential 😃

Very descriptive and informative video. 👍

finnaly a differential that is not 4 studs long and can be driven perpendicurarly. perfect for my all terrain pickup truck moc :D

I'm just annoyed Lego didn't use it in the Land Rover Defender

Really helpful thanks!

Now that is cool technology.

Great video

I like the 2nd gen differential the most. Two-speed operation with no transmission and being able to lock it is a huge deal.

I liked the older one the better because it actually resembles a real diff. The newer one has definitely better functionality though.

I think it's the diff I just ordered and I can't wait to try it !

And the new differential looks like a real car diff, unlike the older one 😉

Good review!! The difference in differential, The new differential differences the rest!!

Thanks for the video, I'll probably order a few of the new differentials from Lego replacement parts.

I have the original differential from the 8860 chassis car. The large gear ring broke off of the rest of the diff body and the 14 tooth bevel gears were a major weakness in the design in that the axles would always slide out.

Bedankt!

I'm waiting for my lego Torsen diff

nice review, cheers mate. Think I'll subscribe :-).

Szia Balázs! Jólett a videó!

Feel like a drive ring like the 2 generation would be nice to have for a "chain drive".

I wonder how easy it would be to make this perform a limited-slip action? I've seen a design that uses belts and an idler shaft to transfer torque from a freewheeling differential output to a held output, but that is limited in the amount of torque it can transfer from side to side. I think a similar but stronger effect could be gained if you were to use clutch gears instead of belts, while keeping the idler shaft. So you would have one differential output that is directly geared to the idler shaft, and the other differential output would be geared to the idler shaft thru one or more 24t clutch gear(s). This would allow you to adjust the amount of torque it takes to make the differential rotate the output shafts at different speeds, which would provide a form of traction control for the wheels attached to the differential.

Super cool, makes me jealous I don't play with those technics or Legos anymore

There were Corner-Gears for the old differential, although they may be rare now.

Thanks so much for the great review as usual. I had recently built the Mack truck and it was constantly “leaking” gears when my daughter plays around with it. I can’t wait to get my hands on this new differential to retrofit the truck with it. Thanks again.

Bruh! My only differential is the oldest one. I didn't expect that. The newest one in the video though looks really nice like it isn't even Lego at all.

music bit too loud, but nice video :)

That redd gear can also have a gear nested inside it for a more standard torque pass-thru.

Hungary hungragy :DD great channel

Any idea what the third last generation, before the latest new differential would only spin one wheel at a time? Any response would be greatly appreciated, many thanks

Great video, but the extreme high energy background music does not match. I recommend something less attentive. Otherwise, huge fan! Keep up the great work!

5 Z12 gears insteded of 3? And clutch for gearbox? Or Z28 double bevel gear? And gear locked inside?

I would use the new differential to make a offroad vihicle, because in these cases it is useful to be able to lock the differential

Yery interesting 👍

Is this upgrade done only with parts of the old transmission?

Cool, I need 25 of them

I like how you can also use the red gear part as a normal gear using a normal frictionless pin

hopefully they add the new differnetial to their digital designer

is it possible to configure it with a different count of gears?

The differential housing which can be locked is golden. (1:30) Didn't know it was possible like that.

I think this new diff will be _great_ for trials trucks!

But you can change old to new one without problems?

I don't know what other people's first thought. my first thought was you can make a four-wheel drive vehicles that can be two wheel drive also easy

Where do you order thees parts??

we've got 4 differentials now?

Thank you for the review! I have a question. I'm using the previous generation diff that is 3 studs wide, and constantly have problems with the half shafts sliding off the bevels and popping out of the diff under high load. Do you know if this diff has helped that at all?

I want to buy this set

1:47 actually, I had a technic buggy set (similar to 8320) which included "crown gear" (part number 3650b), which is able to drive that differential perpendicularly.

hey racingbrick,i have little question,it's not related to this video but,anyway,im 12 and I have build the 42110 (Land Rover Defender) in bout.... 12h not continuous,is that a good mark? I lost some pieces and I have the cracking issue,but, I have the 1st high and 1st and 2nd low gears work perfectly.so,I wanted to now,what do u think bout the 12h mark of time

Could you put numbers of parts used in video?

Can you use the red gear alone without the differential housing ?

I have the oldest one i never knew what it was for

So I'm working on a steam train moc. I want to power the actual drive wheels all 4 of them by powering one axle and connecting the rest with connecting rods (basically Thomas the tank engine style. However I want to use a differential that way the train can make it through corners easier (kinda like the new train wheels coming out.) However because it's a train it makes it extremely difficult at the frame can only be 4 studs wide. Any way anyone have an idea?

Good video but hard to hear you over the music, tone that down.

I would rather the differential before the new one (i think its better)

so it's a combination of all prev generations

I wanna get my hands on a few of the new ones, just wish these double-bevel gears had a proper tooth profile cut into them. The bevel teeth are cut right, but the teeth you'd use for a normal mesh are square cut and bind up, run loud, wear like crazy. And god help you if you try to mesh them with the properly cut old style straight cut gears. WTF, Lego?

I Broke the middle gear of my older Diff as i used a buggymotor to dive it and Put the full Power on it. Also the Main drive gear off my Diff bend all the teeth. But i hate the New one cant be used by my extremly compact under/over gearing becourse it Uses the smaller inputgear. I used always the smaller gear to drive the bigger input directly from the top and used two stackt frames for the whole assambly (if anyone is intrestet, i could make a Video or so. Just contact me 😉 ) Sorry for my englisch, im german

Only issue I have is that you can't see the gears

Nereden nasıl satın alabilirim

I was disappointed with the newest differential. Due to higher torque the red gear pops off of the grey housing and everything stops working. Kinda too bad. I do like the design and will still continue to use it.

🤔👍

I have destroyed some previous old model diffs with the buggy motors and a Buwizz battery. After a while the plastic became weak and started slipping. After the first slip it will almost never drive as good again. Too bad the new gear ratio is so much slower. If you put the new diff in an old RC (moc) model it will go even slower. But if the new diff is stronger I guess you need to gear up before it.

Hello Balázs! meg tudod esetleg mondani az új difi háznak és a hozzá tartoró fogaskerék számát?

i have all of those diferentials

Cost...

👍😀✌

1:47, that's not true, there was a special gear with angled teeth that could drive the diff from a transverse axle.

Ou acheté juste le différentiel en lui même ? Sans avoir à acheter le reste de la voiture ( bien trop cher pour se que s'est..) merci

This right driffential for 42114?

What built the LEGO

Can someone please post the element numbers for the individual parts?

what is the part number of that new differential?

I guess that new ability to lock the differential will make it popular amongst those... Ahem, let's say enthusiasts who enjoy pouring glue into their brand new, expensive RC differentials.

Balázs?! na ez meglepett amúgy háló magyarok

Too bad the set this diff comes in is underpowered. Would love to see some articles/videos from you on modding 42109

I can’t think of anyway do not choose the new differential over the older one.

My differential is damaged

Helical cut gears when?
