Don't worry, there are limiters there, even visible on render.

Oh, I think I got it, thanks :)

@Mechbuilds That wasn't the plan, but I have to admit you forced me to do this sooner than later. So here I am :D After one longer evening of tinkering I prepared front axle with I would say almost perfect pivot point in this scale (just one stud from the center of the wheel). It has couple other upgrades vs axle from Chevrolet, but the most important thing is location of pivot point. I am so happy that I am almost dare to challenge others to come up with better geometry in this size and still keep axle driven.

But, here are some renders. I did not test it in any MOC, but I built it in real life of course and it is solid and works great.

@gyenesvi You mentioned, that you also need small driven front axle, maybe this one above will be useful solution for you? :)

This looks very interesting. Did you already try this upgrade on the chevrolet? Do you get any issues with it? Does the servo get it's 90degree angle without problems while using these CV joints? 
And what about the driveshaft, does it have any issues now that it's not in the center?

I did not try it on Chevrolet and I do not intend to do so. Major changes would be needed in chassis to fit this new axle and the Chevrolet is finished model (but some more additions will be available in future). Using CV joints make this axle not PF servo friendly. And this version of axle, atrough it works like a charm, it has a flaw pointed out by @gyenesvi. I have something in me from perfectionist (at least from mechanical point of view, because creating bodies of MOCs is different story :P) so I couldn't live with this flaw and I already redesigned this version and removed the drawback, and not only that. New version will be used in next MOC from Snowrunner series.

I tried in Chevrolet a new approach, creating a live axle which is suspended indirectly, by creating suspension on linkages and reducing necessary connections only to four. Also this new approach, without involving shock absorbers, is very compact, but, as everything, it also has some cons which now I am more aware of.

I made some additions to this MOC, small trailer and foldable crane. Both are available on rebrickable for free. They will fit to the most of small scale models. I made a video for short presentation.

 

Trailer features:

• live axle with suspension

• openable crate for tools

• lockable, liftable and foldable support for undisturbed ground clearance

 

Crane features:

• compact size when retracted

• located on platform with lockable and foldable supports

• three separately operated sections • rope on drum with lock

• full 360 degree movement with stabilizer

hi keymaker.

I would like to know if it is possible to replace PF servo with PU L motor on the truck?

I won't tell no, but it can be tricky. PF servo is 1 stud shorter than PU L motor.

ok thanks I will have a play later today

I added to the description couple of small (mostly technical) facts about this MOC, which can be missed because they are hidden under rather simple body:

• front and rear axles are connected to the chassis only by 4 ball connections, no suspension elements directly connected to the axles, yet they stay in place and axles have suspension
• suspension uses rubber pieces which allows to very compact and space efficient construction, thanks to that for example rear bed can be located very low – considering fully working suspended rear axle
• even if suspension has a lot of travel already, it is equipped with limiters, which have 2 levels of limitation or they can be easily removed to largely increase travel of suspension
• drive train has four places, where gearing can be adjust, it gives a lot of room for experimentation and choosing your own speed to torque ratio
• all wheels have disk breaks
• it works greatly also with standard 30x20mm rims or 30x14mm rims – you only need to removed disk brakes
• doors have “locks” to keep them in place, they do not rely only on friction between parts
• all electronics is hidden in the floor and power source on passenger place, thanks to that you get clean look, removable rear part of the body and fully equipped driver seat with steering wheel and central column, all of this with keeping great three studs ground clearance which is achievement in such scale and with used rims & tires

I also upgraded list of free additions in the first post.
