still trying to figure out if this is unique to me or if other people are having the same problem. the design of the primary alternator and secondary alternator pulleys are different the secondary looks as if its a threaded pulley threaded on to the shaft and the primary has a nut holding it.
this has happened twice in a row. the first time happened around 1k miles of me tuning the truck aprox 5k total on the truck and the second happened about 100 miles after i tuned it but aprox 1k miles after it was fixed. i know there is a considerable difference in throttle response on a tuned truck vs stock and just wondering if the decel of the throttle response could loosen the pulley?
hell I'd tack weld the damn thing if i knew for sure it was going to happen again. really i don't think i would ever replace the pulley with out putting an alternator on it. so far its been a warranty replacement but its getting to be an inconvenience not having a truck fro a week for a damn alternator
