3 Studs Wide Differential Bracings
Two ways to make your 3 studs wide differential sit where you want it to sit, whatever load applied, and to deal with the half-axles’ tendency to slip out.
The new differentials are sure a great innovation, but a bit tricky to use. They have to me mounted very steadily in order to avoid snapping of the gears, and they still have the tendency for their half-axles to slip out. Here are two simple liftarms-based bracings that solve both problems – they are robust enough to keep the differential where you want it to be, and they use 5.5-studs long half-axles to deal with the slipping out. Each version cosists of 41 parts, and instructions for both can be found below. Parts list for the first version is here, and for the second version – here. Personally, I prefer the first version, but I also appreciate diversity – hence two versions.
I tried to follow the instruction via small picture and finally complete it. The version 1 is better for prevent slip gear than the version 2. I post some new bigger picture for others easier to build
# Version 1

Sure, if you suspend it.
could this idea can be used like the suspension like the scania dump truck?
@gimba96
If your PC has problem opening these pics, then I have no idea how to make a downloadable version it can handle.
@Sariel
I know but my pc cant open the pictures.
So i thought maybe you could a downloadeble version
I’m currently modifying the lego crane truck with a diff lock, while trying not to alter the model to much. The main problem I am having is while I need the gears around the differential itself it means it can’t fit in a strong brace that is compact enough and wont slip off the drive gear. Any suggestions?
@joalegofreak
The instruction is like 30 pixels above your very own comment. How did you manage to miss it is beyond me.
could you add instrutions?
@joalegofreak
BRICKLINK!
where do you buy those differentials?
@Adi
Cool. I’m not sure how would the knob wheels work with a really huge load. I’ve seen some cases in Truck Trial vehicles when huge torque caused the knob wheels to transfer the drive unevenly, in small ‘jumps’.
I did it!! Instead of using normal gears I used the Knob Wheel gears and they work really well.
@Adi
So there’s your answer.
The gears always slip.
T’ve tried but no other ways work.
@Adi
Are you sure this is a smart question?
I really want to make this but i dont have the differential. Is there any other way to build it.
@Prakash.K
These are not kits, and if you need parts to build them, you can do it at shop.lego.com or bricklink.com.
how to buy these kits? What will be the cost? Where are all it is avilable in india?
@Boris
MLCad.
I think all of your projects are awesome! Just wanted to ask you, in what program do you design some of your projects?
The second has a big advantage: the support of the axis that supports the 20T is not mobile. But i prefer the first version :p
