Lessons Learned:
If you have any thoughts that you might have unduly stressed the hub, =
please
consider replacing it. I would suspect that you have. At least crack =
check
with the best method available.
It WILL break. The good news is that when it does, it will not allow =
the
wheel to depart from the car, and you will just come to a stop. I broke =
one
at Blackhawk Farms Raceway and decided that the other hub is likely to =
break
too, since it was subjected to the same removal method & stresses. It =
did.
At Mid-Ohio....borrowed one that had been removed with a big press (I =
think)
and it broke too. (Someone located a complete assembly and I was back =
in
business, again)
I might have a hub or two extra, if you need one, BTW.
After seeing 25 ton presses cause folks to run for cover and factory =
tools
not get the job done...I have another method that COULD be done in
combination with the above.
I heat soak the hub and then cold water quench, and then reheat.=20
I have a =BD" industrial composite pad that looks like nylon and with =
the nut
flush with the end of the shaft, I drop the shaft & hub sharply =
downward on
the pad. If it doesn't break loose I repeat the cycle. I think the =
"heat to
cold to heat" shock cycle breaks the bonding of thirty years. 100% =
success
rate with little effort required, so far. No damage to nut or end of =
shaft.
My only concern is that I might Brinnel the bearings, with the drop to =
pad,
but I have see no evidence to date. In any case the hot & cold cycling
could be used in conjunction with the factory tool or a press, if you =
dont
like banging the shaft. Sounds better than a BFH, tho... :-) I am =
sure
there will be more opinions....and they are welcome.
Let me know if I can help out with a hub...I can take a look at my =
stock.
I am also going to put the arm on you for your attendance at BRIC, =
doncha
know. Even if you dont bring your car. Please try.
Regards,

Amici,
Because of a leaking grease seal, a couple of weeks ago I took my
axle to
Bob Wagner @ Atlanta Imported Auto Parts. These guys are a great
source of
help for both funky parts or troubling mechanical work. De-mating
the axle
hub from its nesting place qualifies for the later. Bob's 25 ton
press,
however, was unequal to the task. Success was gained only after
securing
the assembly (axle and huge wheel puller) to a monster vise mounted
on a
steel work bench. With a series of Micky Mantle swings of a 16 lb
sledge,
with a gratifying report the 30 year old bond yielded. The high
point of
the whole operation was Bob's third swing... which was a clean
strike. The
batter was sling shot a couple of meters across the shop by the
momemtum of
a Mighty Casey swing. The power blows which ultimately succeeded
frequently lifted the entire work bench off the floor.
Whilst mopping his brow Bob offered, "Yup, that one was pretty
stuck."
