Leaky Steering Box with knocking(with pics)

I am posting about my power steering box it has what looks like a missing seal, it has shot out some oil and fluid, is there both inside a box? so decided to take some pics to show you how it is looking, I can get hold of power steering box with arm, anything else I need? tell me what you think...
The bottom of the box, where the arm comes out, missing seal?



where the arm connects to the rod? not sure if the bolt is bent?




Thanks
Liam
