How to fix the cracking noise of the LEGO Technic 42110 Land Rover Defender

I read a lot of negative comments online about the gearbox of the LEGO Technic 42110 Land Rover Defender, lot of people saying that it does not work at all for them in higher gears, all their get is a terrible cracking noise and the fake engine is not running.
I explain in this video what can be the root cause and show you a potential fix. Please note that this is not an ultimate solution, this covers one of the most frequent reasons but will not fix it every time. For a more detailed guide about the issues and fixes please click here - racingbrick.co...

3:06 Even my wheels rotate backwards also the fake engine pistons work (I'm talking about my 4th gear /HI) Should I open my model and check the U joints again? Or I should check something else too...

[@tomdreesen1948]

Same here. I finished the build last night and the rear drivetrain runs sluggish and cracks when driven around. U-joints are fine. I really think the problem is in the rear drivetrain because running the front wheels goes fairly smooth. It's the rear wheels that are the problem. All the connections seem to be right, at first glance. Anyone got a fix or point in the right direction?

[@nappie333]

Great video. To all people who still have problems after this mod. Don't slide the u-joints all the way to the end of the axles. Let it be losen a little bit.The shaft will be restricted in it's movement If you slide the u joints all the way to the end of the shafts, which in turn will cause cracking noise and stop movement of the wheels. This solution together with the solution of racingbrick fixed my problem and the gearbox is running like a dream now.

[@reza42145]

Hi, you mean the axle within itself (the one which has u-joints at both ends) or the axles coming from the gearbox to which the u-joints get attached?

[@ThePulmentinum]

Also the fact that the U-joints work at a very high angle contributes to the problem.

[@ranow3389]

Thank you for this fix video. After final assembly, I didn't have a cracking issue but noticed the selectors didn't seem to do anything. Spent 20 minutes trying to do a minimal disassembly and noticed that one of the joints was off set. Normally I keep them in line, but not this time. Fixed and the issue was resolved. Thanks.

If you still have issues I suggest to remove the body, then go through the whole drive train and double check everything as it is presented in this video - kzbin.info/www/bejne/qmq5gnqlps2CfNU It is also possible to disconnect the shafts going to and from the gearbox and check the sections separately by turning the gears manually. Here's a hint how can you remove the body in bigger pieces - facebook.com/Racingbrick/photos/a.642361079222005/1486442398147198/

[@tom7956]

Hello. Like your video very much. Just a short question. I have checked my U-joints and other stuff you proposed. And still have the same issue. Funny, when I put gear in R, all gears work perfectly without cracking sound (HI, LOW, all gears) and motor simulating cylinders movements. Only in D I have explained issues. Any comment on that? Thanks.

[@RacingBrick]

@@tom7956 I suggest to check this video - kzbin.info/www/bejne/qmq5gnqlps2CfNU In R your gearbox is not involved, the fake engine is driven directly so hi/lo and the gears does nothing. I suggest to remove the body, disconnect the shafts going to and from the gearbox and check the sections separately

[@DanyFil231]

@@RacingBrick i watched your video changed details and my Landover actually doesn't crack. I fixed it with your help

[@zackirstein9233]

I only have this issue when moving the defender forward in drive high or low, but when I move the defender backwards, even in drive high or low (or reverse - yes I know R bypasses) there are no cracks, albeit the pistons don't move completely smooth. Why is it cracking when my U joints are aligned?

[@alilatif812]

I just finished stage one and found that when I spun one wheel the other was reversed. I reversed the differential multiple times without luck. I ended up tearing it apart. Right before attaching the gear box I tested the wheels and they spun the same way. After I attached it they were reversed. I've triple checked the gearbox. Do you know what's going on? I'm probably just going to continue.

[@maxburmab7962]

Guys, I’ve spent a lot of time trying to find out what was the issue that caused the cracking noise and I think that the most popular “mistake” is in the fake engine itself. Little 2:1:1 pieces that are rotated by the axle in the engine might not be placed perfectly and then it becomes much harder to rotate while touching the wrong fake cylinder (red one). And sometimes when it cracks, the engine stops working on any other speed. It is because of the dark bluish grey connectors between the seats (and near the + - sticker). They just get further from each other and don’t let the gears rotate properly.

[@captainclaypool5582]

SOLUTION FR + EN/ SOLUTION IN ENGLISH (translated by browser) BELOW FRENCH Si comme moi lors du premier montage, vous avez eu cette frustration en essayant votre nouveau Land Rover. Dans mon cas, après le premier montage et en dépit que tout soit bien monté ET que les arbres de transmission soient bien alignés, les vitesses craquaient en Low ou en High à partir de la 3ème vitesse. La 4ème vitesse en High craquait à mort. Bref, sans grand espoir, j’ai tout de même tenté un démontage et remontage complet MAIS en veillant à laisser pour CHAQUE engrenage (ou TOUT AUTRE PIÈCE TOURNANTE/MOBILE) un petit espace (juste ce qu’il faut pour que ça ne frotte pas), afin qu’il y ait un minimum de frottements entre les pièces mobiles et les pièces fixes. Ce qui a son importance vu le nombre d’axes et d’engrenages par lequel s’opère la transmission depuis les roues jusqu’aux 6 cylindres. Et là miracle, toutes les vitesses marchent sans craquer, même si ça manque toujours de fluidité (en 4ème High surtout). Mais ça ne craque plus jamais ! Tout ce que je peux vous dire, pour ceux qui (re)montent, c’est de bien tester la boite à vitesse (directement en 4ème High) dès que vous arrivez à l’étape de la pose du volant, en mettant les 4 roues en place au préalable bien sûr. N’hésitez pas à la faire rouler en l’accompagnant sur 2 à 3 mètres pour vous faire une bonne idée et ajuster si besoin est. Et une fois que c’est acceptable pour vous, vous pouvez continuer la suite en veillant à ne pas trop malmener la structure afin de ne pas compromettre les différents serrages établis. En espérant que ça en aidera pas mal et courage à ceux qui doivent redémonter. J’ai moi-même longuement hésiter à le faire sans savoir si ça en vaudrait le coup mais je ne pouvais pas me résigner à avoir un Lego à 150€ dont la fonction principale ne marche qu’à moitié. ____ If like me during the first assembly, you had this frustration while trying your new Land Rover. In my case, after the first assembly and despite everything being well assembled AND that the drive shafts are well aligned, the gears creaked in Low or in High from the 3rd gear. 4th gear in High creaked to death. In short, without much hope, I still tried a complete disassembly and reassembly BUT making sure to leave for EACH gear (or ANY OTHER ROTATING PART / MOBILE) a small space (just enough to keep it from rubbing step), so that there is a minimum of friction between the moving parts and the fixed parts. This is important given the number of axes and gears through which transmission takes place from the wheels to the 6 cylinders. And there miracle, all speeds work without cracking, even if it still lacks fluidity (especially in 4th High). But it never cracks again! All I can tell you, for those who (re)build, is to test the gearbox (directly in 4th High) as soon as you get to the stage of fitting the steering wheel, putting the 4 wheels in place beforehand of course. Do not hesitate to roll it by accompanying it for 2 to 3 meters to get a good idea and adjust if necessary. And once it is acceptable to you, you can continue following it while being careful not to manhandle the structure too much so as not to compromise the various tightenings established. Hopefully it will help a lot and courage for those who have to restart. I myself have long hesitated to do it without knowing if it would be worth it but I could not resign myself to having a Lego at 150 € whose main function works only halfway.

[@TinkeringJohn]

At 2:11, the right image is step 89 on page 59 of the instructions. I just got this set 2 days ago and although my book has the same picture, the online pdf instructions shows the correct alignment of the u-joints in the inset. I just realized that although the inset is wrong in the book and in this video, the main image shows the u-joints correctly aligned.

[@AN2Felllla]

Looks like LEGO have fixed the manual now. I'm up to this step on my Defender and both of the joints are in the correct position.

[@BorjaVarona_at_YT]

I am not totally sold on your recommendation. I have properly aligned both universal joints according to your instructions. My main concern is that the gearbox works incredibly fine when the car moves in reverse (i.e., backwards), regardless how hard you push it, even in Hi-4th gear. On the contrary, when you push the car 'drivewards' the gear box is a complete mesh in 3rd and 4th gears. I suspect it has to do with torsional torques in the shafts, and I would like to know if somebody else is having issues with it.

[@RacingBrick]

I did not say that the U-joints can be the only source of the problems, I suggest to check my pinned comment above. Btw in reverse the gearbox works incredibly fine because it does not drive anything, in reverse the fake engine is driven directly bypassing the gearbox.

[@BorjaVarona_at_YT]

@@RacingBrick Thanks for your answer. I know that the gearbox works fine in reverse because the 'selectors' are bypassed. What I meant is that when you have the model in 'Drive' mode with Hi + 4th gear, you can push it either frontwards or backwards. In the latter my gear box works like clockwork. However, pushing the car frontwards produces cracking over 3th gear. Probably, I am going to rebuild the car in 'British mode', to see whether I can reverse that behaviour (frontwards vs. backwards) or not.

[@BorjaVarona_at_YT]

I have disasembled the model completely and gone back to step 1. I intended to rebuilt the model alla 'British' but in the end, instead of flipping right to left and left to right, I found it easier to make two small changes: in steps number 4 and number 134, I just swapped the position of the differentials. Of course, in steps number 89 and number 90 I have properly aligned the U-joints, as originally suggested by RacingBrick. Also, I have paid careful attention to assemble the gears with enough gaps to reduce friction at all times. Now, my Land Rover's gear box runs like soft butter, whithout barely any sign of friction when pushing it forward.

[@para3z]

@@BorjaVarona_at_YT Swapping the direction of the rear and front differentials worked for me also! I had tried adjusting every gear I could access without a complete rebuild. There was cracking from the gears only when moving forward in D on the two highest gears. Now there's only cracking when moving backwards in D on the two highest gears. As you shouldn't really reverse in D, this is not a problem. :)

[@travcool1991]

This isnt just a lego issue. People with insane lifts on their vehicles snap axles and driveshafts all the time and wonder why.

[@nathanthompson7399]

I did everything you said and still had some clicking in hi and lo 3rd and 4th gear. What I figured out is that Lego put the 2 differentials in backwards so I flipped them around and now I have no issue at all in any gear combination

[@chandal804]

[@eloicoloma7842]

Great video. Thanks! It helps me a lot. I have checked that Lego has fixed this issue updating the online instructions and setting the shafts exactly as you do. Apart from this, I've also checked that the fake motor gears cascade is the other origin of these cracks (apart of the u-joints issue, of course) because it does not run very smoothly. If you disconnect the light gray shaft to them, everything goes fine. Interestingly, if you spin the gears with the chassis upside-down, the motor spins smoother. I think that is something related to front chassis torsion. Ironically everything works also fine when you move the car backward!

@RacingBrick hello fellow, I've noticed the same problems with my own model saldy :/ I've put attention on having the u turn axles both the right way and I've also pulled up the DNR connecter a little bit up which I think helped the model by a little but still the cracking noises.. Your videos are really helpful but I don't really have the time to watch em all and then fix it, it still has the cracking noises and I wanted to ask if you know what could be the problem then? I know that I did not use wrong gears since I am a really perfectness loving and accurate brick builder it can't be that I used a wrong brick, surely nobody is perfect but I paid a lot of attention to using the right bricks since I've noticed before I got the model that it has such problems and now I'm standing here with a mark on my face T-T I guess I'll just have to rebuild the technical parts and then put it all together again... If you know what else could be the problem then pls let me know, have a nice weekend though!

Hi guys! Went through all these amazing videos but still facing the cracking issue While in D and hi gears, I feel kind of stiffness I'm pretty sure I've assembled everything in a good way.

[@prosanis1216]

Wouldn’t it be better if you'd mount it with gears instead of the universal joints? Of course you are right that you have to align the shafts but it’s puzzling me why they didn’t use gears in the first place?! Nevertheless I would like to thank you for sharing.👍👍

[@zeichnerkollege]

Superb tip. Thank you.

[@4greenkoalas]

My U-joints are correct but I still feel some mechanical resistance in the model. In the higher gears that resistance acts like a pullback motor until a gear slips

[@Mitsurugi2424]

I probably need to rebuild mine. The gearbox has a bit of rolling lag before it moves the pistons and there is generally just some slop in the gears. Going back over the pages multiple times, everything looks to be in the right place. And I have no clicking or missing. The gearbox just isn't that impressive I guess...

Mine cracks in 4 gear, and the wheels rotate when I push it forward and lift it, just like showed in the video, but the U-joints are assembled the right way, as far as I can tell 🤷🏼‍♂️
