Alternator Denso or Duralast

On my 2010 Corolla I replaced it with a Duralast one and it lasted a couple months, then I replaced it with a Denso one and haven't thought about it since. Cars got almost 250k miles on it.

I supply Denso alternators for d3,4 Rrs

Denso is the OEM. I chose to rebuild mine with new bearings and brushes from Honda. The rectifier was the actual bad part, though. I put an aftermarket rectifier in for $30.

I got denso on my car and it's perfectly fine

Denso by a very wide margin. The rest are not even close in quality.

Buy Denso remanufactured alternators only. Many many people have reported problems on Odys and Pilots with other brand alternators. Remanufactured and in a Denso box is what you want.

Been running a duralast in mine for about a year no problems.

Drives fine, maybe a bit of whirr from the alternator area but hard for my ears to tell of that's out of normal none of the unhappy noise from before battery kicked it.

Denso is usually one of the top ones, if they've tanked in quality I shudder to think how bad oem GM, and mopar/stellantis has gotten. I still have nightmares from absolute shit quality of GM parts, alternators and starters barely lasted over a year.

The alternator of my Corolla died. I bought a reman Denso alternator from RockAuto and made the swap. However, the new alternator makes a loud, screeching sound when I start the car. It goes away after a minute-ish.
