Not in my book.. I've never had to replace an alternator before 85K on any of my vehicles. Maybe I've been lucky.. That's probably a good rule of thumb for a water pump though... That or 70K. Ben
Read the full replyJust replaced my '98 'burb's alternator for the third time.
My experience is that an alternator is good for about 60,000 miles.
Does this sound like a good rule of thumb?
If so, the next one's going to be a premptive replacement 50k miles from now.

You got lucky. CS-130's don't last that long. CS-130D's last just about that long. BTW, Was it a diode failure? Hope you got a decent rebuild.

Many times the brushes wear out. Try just replacing them for $5 or so.

RE/
Don't know enough to say.
The diagnostic machine said "Low Output" on this one.
Was 400 miles from home and it was July 3rd - so I didn't shop around. Connected the spare battery I always carry, nursed it to a NAPA store about 40 miles away, took what they had (rebuild) and got a guy down the street to install it.
Got back to the place I was staying at with a total elapsed time of 4 hours. A lot better than the 4 days I was anticipating...
The 60k figure I blurted out came from a combination of what the NAPA guy said ( "about 65,000 miles") and my own experiences.

Maybe I'll start carrying one too.
How hard is it to replace in the field? Seems like the main problem on a Vortec 5.7 would be the serpentine belt.
