  • Duralast alternators are quite expensive. The price starts at around $125, and it can reach up to $510.
  • If you are about to mount the alternator all by yourself, then do not expect any assistance from AutoZone since they do not provide any customer service. Also, they won’t replace the alternator for you. However, they can test it for you if you bring it in by removing it from the mounting.

A member of the CarTalk community, db4690, expressed his disappointment over the Duralast alternators like this,

“From a professional standpoint . . .

I’m not a fan of ANY store-brand rebuilt electrical items, such as starters and alternators. Every time we got one “in a pinch” because the vehicle had to be ready asap, we ended up regretting it because the part(s) didn’t last very long.

I watched my colleague go through FOUR alternators before he finally got one that actually worked. And they were for a Ford, coincidentally. Don’t be surprised if the alternator lasts 3 years or less. There are lots of choices between store-brand and dealer, by the way. It doesn’t have to be one extreme or the other.”

“I have used the Duralast on couple of other vehicles with excellent results, most recently was on my 98 Jeep Cherokee daily driver, original one went to 150k miles & died, I replaced with a Duralast lifetime & it went another 8 years & 60k miles with no signs of failing, sold the jeep 2 years ago & still see it driving around town on I assume the same alt.”
