So, like the title says I've gone through 3 alternators in a month. I replaced my original alternator after 127,000 miles when the charging stud snapped off (no idea how this happened). I had one new alternator from autozone, bad regulator, then 2 alternators from rockauto, 140 amp Ac Delco new units, bearings in both of them have gone out fairly quickly. What could be causing this or is it just my s*** luck? I'm getting really tired of replacing these damn things.
