I found this tear down video back when I acquired the 3500 bearing/hubs.
Kinda interesting that it looks like they had a problem with heat
treating and the shape of the hub/bearing surface:

It's not a long vid and I have it starting just before the guy shows
the bad area...

I wonder if they have a machine that rough and finish turns it, mills or
broaches the sensor ring and grinds the bearing races in one chucking.

That sounds like something Ed Huntress would've known or who to ask.
Really miss some of the old sources of info😑

I was a bit surprised to see inside one of these "throw away" hubs and
how they were being designed. A neighbor was having trouble with front
wheel bearings on a Lumina. I kinda figured his friend doing the work
was torquing it to an incorrect value. After seeing these 3500 hubs
pulled off a friends truck I looked up the Lumina. Sure enough, it uses
these throw away hubs. Torque setting is already done. Just install it,
hope it works right...

The only auto factory machine I've seen in operation made AC spark plugs,
and the actual pressing operations weren't visible, only the rows of
incomplete plugs running around the walls of the little stand-alone booth in
Flint.

I quoted a test station to measure alternator rotor outputs and found out
how they are made; everything pressed sequentially onto the shaft, but I
never saw it done. AFAIK spark plugs are assembled the same way.

Hi Jim and Leon. I guess my ears were burning. I haven't looked in for a year or two.
'Sorry to disappoint you, Jim, but I don't know the answer. I am really, really long out of metalworking. However, that is a job that certainly *could* be handled by a multi-function machine. The multi-function turning machines we sold at Wasino years ago could have done it. Although a grinding spindle could have been applied to finish it, my gut feeling is that the grinding would have been done in a secondary operation, on a precision grinding machine. But, maybe not. The limiting factor on that kind of operation is the ability to get the grinding concentric to a very high degree of accuracy.. Secondary spindles on a multi-function machine are pretty marginal in that dept.
I hope everyone is well. I'm sorry to hear about Gunner. I'm well. Hasta luego.

Good to hear your well and about. Past few years have been pretty
bad for the older generation...

A former neighbor moved to New Mexico while her daughter remained local.
Some time after the daughter got a bad feeling that something was wrong and
called her mother, who answered that all was fine. A moment later she said
OH NO!, there was a fire in the kitchen. She didn't survive.
