Replaced the alternator brushes. There wasn't a 'rebuilt' 'refurbished' sticker in sight on the alternator....'Toyota' 'Denso'. 267k miles...replaced with oem brushes. Expect another 250k miles. If I knew how to upload pics of the old/new I would. FYI...not sure where I read it, but if you're have alternator issues (the alternator light illuminates on the dash), if you lightly hit the front of the alternator housing with a hammer and the light goes off, the brushes are the issue. Fairly easy to replace.
