not sure why op did not want heat, all the braking parts get hot when the
brakes are applied in normal use. A little extra heat does no damage it just
eases the removal. Bearing must be tight in the hub because with normal
running heat the hub expands but should not increase in diameter whereby the
bearing becomes loose even though retained by c'clips.

In a pinch I have used a heat gun to help warm things up a bit.  It has
worked for me a couple of times.
This is when I did not want to use the blue wrench.  I just have to refill
my tanks.  ;-)

Are the rear bearings that hard to do?  I have done a rear wheel bearing in
a 1990 Audi V8 (IIRC) and don't remember it being that bad.

Did you use some Rust Penetrant?

Broke down and bought a 20ton. 12ton broken. 20ton made that bearing squeal,
then bang, and it popped out.
Really didn't want to torch it.

What is the trick to removing the rear wheel bearings? 12ton press does not
begin to press it out.
Was able to press the hub out. Just not the bearing.

Torch to me, is the last resort.
