Alternator OEM Toyota or Bosch

In your case I would say just buy a new replacement alt from a name brand like Delco Remy or Bosch, none of this parts store rebuilt junk, you'll just be doing the job over again soon.

Bosch, Valeo, or Denso would be my top choices. Don't get a Chinese one. Shit won't last at all.

Bosch makes (made) excellent rebuilt alternators and I’d check them out.

I bought a Bosch alternator at O’Reilly’s for ~ $300 and the gaskets at Autozone for ~ $100 (you can get them cheaper but I needed them quickly)

I would use the BOSCH from fcpeuro.com without hesitation.

I replaced my alternator two years ago, and I put in a Bosch, and I haven't looked back. It works great and also has a warranty.

Even brand name remans like Bosch and denso are suspect but generally much less so.

Someone warned me against going with auto parts store Remanufactured because they had to do it 2 or 3 times before they got a good Alt, so I stuck to OEM.

Alternator has been replaced 2 times within the year battery is also new and the odds of 2 brand new faulty alternators is pretty slim.

Ive had a few Bosch reman failures lately at my shop as well, although they were for N52s, all bearing noise after about a year.
