Long story short, I ended up replacing the steering knuckle + hub. For
$200CAD I got the whole thing from a scrap yard. It is in excellent
shape (compared to mine) and even the wheel bearing looked new.
The brake disk and the holding screw came off it without a hitch, I
swapped my strut insert and coil spring, used the better thrust bearing
and it went on the car asap.
New brake disk and pads went on, I made sure to use copper grease on the
biding faces.
The car runs great, no more vibrations or noises and I did an alignment
already (had to put winters on anyway).
I took the old hub and stuck disk to work, where we tried using all
kinds of presses, a torch and a hammer chisel. The disk is not coming
off the hub. So me and my 4lb hammer and a wood block were going nowhere...
In the long run, I think I made the right decision.
200,000 km and running great!
Thanks all for help, Ben
