Artteacher, sometimes mechanics don't turn rotors because they are beyond the safe limits to fight heat and prevent warping. But I agree, some folks are just part changers, whether for profit or just laziness.

This is a good time to ask. Has anybody here ever had a starter rebuilt? Guys around here rebuild starters and alternators all the time. I just got a 140 amp alternator for a Mazda B3000 for $97 with a year guarantee. I upgraded from the 95 amp alt at a shop about 20 miles away. I remember going there with my dad about 40 yrs ago. Family business. If the idiot mechanic hadn't thrown pantinosm's away maybe it could be rebuilt?
