I can remember have our 80 ton press involved with removing the hubs. Lots of
pressure then a great whack with a copper hammer was needed to remove the
parts.
It was found the two parts, hub and axle had welded themselves together as
there was metal transfer, such as you might see on a main bearing in the block
when the torque was not high enough. Agreed, the hub comes off with a great
"whang".

I've pressed a lot of these things apart and I've never broken an axle or a
hub in racing duty afterwards, I switched to Southwick strictly as a
prophylactic measure. I've used the aftermarket axles and slowly sucked
them
deeper into the hubs without real problems. I considered it worthwhile to
break all the stress risers I could think of with a little radius even on
the
stock axles and hubs--sandpaper or a stone works fine. .
there's no magic I can see in the puller--it pushes the axle out with a
screw
instead of an 80 ton jack. I support the hub with a special plate I made.
Seems to work. A good lateral shock is sometimes a good idea--yes, that
means
hitting the hub sideways with a hammer while the press is grunching on it.

I've seen a rear hub resist an oxy torch and an 80 ton hydraulic press!
It is my belief that if you press the hubs off, (as opposed to using a
puller) the hubs will be damaged and eventually break.
(I've broken 3 under racing conditions)
Until the hubs are removed they never seem to break.
Get a very big puller.
Resist the urge to use a press.

Hello All:
Today's project was to install new rear brake shoes on my TR4. Pulled off
the
brake drum and...oil on the shoes and on the drum surface. OK so I ordered
up
some new seals, rented a hub puller and following the instructions in the
shop
manual, proceeded to pull the hub. However, the hub doesn't want to move.
Not being an advocate of forcing the issue, thought I'd poll FOT to get
some
suggestions. Apply heat with a heat gun to maybe loosen things up? Other
thoughts?
