That might have been possible but probably not the best method. I have done stuff like that too on my old fj40, but ended up having to redo the job again cause it failed. So spending the money on cheap axles now hopefully will save me later.
I found one once where the PO had put the seal in backwards, I assume it was done that way to contact the axle in a different spot, and it must have worked, it wasn't leaking when I took it apart and replaced the axle.
