<<<<My
alt. problem ended up being a rear bearing failure, as I took the regulator
to see how the brushes were, and remnants of bearings and dust shields lay
on the bottom...>>>>
Are you sure the rear bearing failed? Years ago I thought the same when the pulley had lots of up and down play. Disassembly revealed the plastic bearing carrier got loose and spun w/ the rear bearing, which wore out the bearing recess in the rear case half. It was so bad the rotor had begun to rub the field coils. I used aluminum (the real) duct tape and wrapped it around the bearing as a "Temporary" fix to take up the slack. That was in 1992. The alternator failed last year! Got at least 9 years and about 150,000 extra miles out of it! It got replaced w/ a $40 e-Bay special that was recently rebuilt! Talk about luck.
