Ya I figured I need to space the links vertically more to make them work more reliably. I'm gonna try a few ideas with the axles in the next few days really like to make the axles as strong as possible while being easy to make into a steer axle for the front (only have 1 free u-joint atm >.<)

I'm digging your design an I can tell ya sariel has some great info on multi gear transmissions that may give you some ideas how to implement in your build.

I did finally figure out how to set my links so they won't dog track. ATM I'm fiddling with some 6L links though I think the longer 9L ones would work better for a longer wheel base. An I do have a test axle made though it desperately needs a redesign they spread apart to easily will have to look an see how some other folks made their axles work an try to implement a diff an locker. Its kinda hard for me to atm order or buy sets for parts cause I'm saving up for a 3week vacation in Europe which I'm excited about since it will be my first time out of the USA. Also I know this is probably overly complex for a truck trial like vehicle but I tend to think in a over complicated manner doesn't help that I've also spent a year at a technical collage learning about large diesel chassis an engines

This is one of my first 4x4 I've been trying to complete with the new PFs. Basic functions -1XL motor driving a 16t to 16t using technic conveyor links (don't have normal chain links >.<) that then drives a 8t to 24t differential -1M motor for running a mini LA directly to pull an push a older pneumatic piston (will be replaced with a newer one likely to be modified for running water or RC shock oil in) -1M motor running a auto valve to open an close the center diff locker. --------- Things to be done -Improve drive train gear ratio make it more torque oriented -Create proper 4link connected live axles -Build a truck body maybe a 80's F150 or Chevy On each side of the V6 engine is the M motors...Hopefully this will help with weight distribution The auto valve that runs the small bidirectional piston for the center differential locker Its probably unusual to see the lego conveyor links being used to actually drive the gearbox but I'm trying really hard to work with what I have This piston does work but its over 14years old an I think a member on the forum had issues with hydraulic steering with older seals leaking all over the place edit--- Forgot to mention I'm having a issue with making 4 link suspension that doesn't swing side to side excessively causing dog tracking (NOT GOOD >.<) an I want to see about putting the newer diffs in the axles an implementing a pneumatic locker for each axle aswell

New here but I've got a idea for just using pnuematics that might work but not totaly sure why not use a steering rack an add some extra gearing to it for a pnuematic compressor so you don't need to manually recharge the system? An by steering rack i mean like one out of the new backhoe to move the piston in an out that be possibly smaller profile then the MLA compressor. Love the idea to use pneumatics on the axles that would make more compact an more suspension travel.
