Wow, thats a whole lot of joints!  I'd simplify the model somewhat - 
most vehicles are simulated with purely a box and 4 spheres on hinge2 
joints, and people have enough problems with that as it is.  For my own 
model I've got a box with 4 ccylinders on slider2 joints (my own 
replacement for the slider, which I found unacceptable).

You stated that the setup generally works without the last hinge joint - 
perhaps this is an acceptable way to go?
