Sorry, Jim may be a cynic.. as a professional shop guy he ALSO has to put
up with blanket aspersions cast on his trade, which colors his responses.
Not to mention, some asking advice seem to want to receive step-step
instructions rather than spending a few bucks for even a general
reference book, like Haynes.

THAT SAID, if you reread what you and he wrote, I think you'll find it
was you over-reacting as much as you think he did.

Inside, the procedure is pretty straightforward... once you get to the
gear carrier:
Remove lock bolt, remove pin, push axle in, remove keeper clip.

When you see it, you understand why Warman said replace other axle seal
while you are at it.

The ONLY trick that may help involves refilling lube, which is sort of
awkward for the driveway mech.

You might consider measuring lube, based on mfr capacity specs, into a
sturdy sealable plastic bottle with cap modified to pass two pieces of
tubing, first from bottom of bottle, long enough to easily reach filler
hole.

The second just into bottle; both sealed around cap holes.  Then apply a
low pressure air, 2-3 lbs sq in, or gas source to push lube up into
carrier.
