Really,
They really didn’t tell us much?


Bones

 

I think that there is a shackle attached to the back side of the axle and that is what you can see near the radius rod bracket.

Roo

 

You can almost see the spring behind the axle. I think Roo is right. You can see the angle of the axle though if you follow the friction shock rod.
