Greetings Fellow GMC'ers :
Just got done listening to this audio clip and now I am wondering if there really is a linkage. Seems to make sense on one level.

I also know our vehicles seem to hold a large amount of anti-freeze and
I happen to know James Morris, the host of the radio show, and think he's a thinking mechanic.... So I pass this along as furthering the discussion .... not endorsing it.
Appreciate your thoughts.

Wow,
There was a lot in that clip.
We all know he was right about using air wrenches during assembly and particularly to set up bearings.
The bit about AMC transport causing wheel bearing failures is confirmed history.
The premature failure of front wheel bearings on C and K cars was a known issue, but there were also lots of other things going on with new stuff. Like unit bearings in FWD cars - aluminum radiators and lots more plastic. If this were really the case then, why don't we still see it in vehicles less well maintained?
I have done a goodly amount of chasing stray current around car bodies. I have found any that originated in the car and went out through the wheel bearings. Under any operating conditions, it will be hard to develop anything more than a static level charge.
As to 4~500 mV between the coolant and the body (using the negative battery terminal is going to show other things) will probably cause massive electrolytic corrosion in anything that can be anodic to the rest of the system.
