How Many Miles Do Alternators Last

How Many Miles Do Alternators Last. The one on my 03 Explorer lasted about 8 years 145k miles. Some new alternators may carry a limited lifetime warranty.

I was wondering if I should have the alternator rebuilt new bearings by a local shop near me. Most car owners may anticipate their alternator to last anywhere from 60000 to 150000 kilometres. Alternator life is so variable and how long an alternator lasts depends on so many factors.

IMO 135K is a reasonable amount of life out of an alternator and not necessarily premature or unusual.

When your alternator is on its way out you may start to lose power to your various electrical components when your car is at. On average you can expect your car alternator to last between 5 and 8 years. Generally speaking you can expect your car alternator to last anywhere between 40000 and 100000 miles.
