Making of Quad bike by Ali Ismail

and here how I done it. I just placed a bone for the horizontal axe and a bone for the vertical one gave both of them an IK chain. I connected the horizontal IK controller with a circle I have done but for the vertical IK controller I connected it to a dummy object connected with the horizontal bone.
So when I move the circle it will act as a real axe
This image makes it more clear.

for the spring it self as you notice from the previous images it does work as a spring. I just used wire parameters and made the position of the circle control the height of the spring

for the back spring same as front but instead I made a metal chain which actually loops correctly when the back wheel rotates
I made the chain using path deformation then controlled the percentage of path by the rotation of the wheel, simple but it works
Steering also is rigged
To control the rotation of the wheels according to the steering I did use strange method to quickly make it without using wire parameters and figuring out the right axes and parameters
I placed 2 dummy object in front of each wheel as in the image and constrained each wheel to look at target to the dummy then linked the dummy to the steering, that way when the steering rotates the dummy will move with it causing the front wheels to rotate accordingly
I hope this image makes it clearer
The right way to do it would be to use wire parameters or max reaction manager (set driven keys in maya) or and orientation constraint if possible
