Is the front seal in PS pump easy to change?

I MEAN THE BOX. (power steering box) I've had hell with this power steering system. Changed box out to reman 86 SS Monte fast ratio. It looks like it's leaking at the front. Is this something I can change myself? Have never been in a power steering box before.
