Autozone is no different than any of the McParts. They have some huge rebuilder do the starters cheap and they have the capability of returning any of them that don't make the warranty period.

They have no control over the quality..........just the price and the warranty..........that's the way they like it.........so they can sucker folks like you with a low price.

Even if the starter works properly, it's unlikely to last more than a couple of winters unless you don't need to crank it much.

I put a Bosch rebuild in the SD..........we'll see if I can get 10 years out of it.

I hate doing the labor twice.
