Pinion Oil Seal

[wxman1]

Well the pinion oil seal is leaking
on my 69 C10 P/U. I never changed
this thing before, so a friend of mine
let me use an old rear axel off a junker
to play with. I tried to remove the pinion nut
but no dice. I'm using a pipe wrench to hold the
companion flange (where the u-bolts bolt
into) and a 1 1/8 six sided socket on the pinion
nut with a breaker bar.

Is is possibly a left hand thread? Anybody done
this before?
