when I searched your vehicle. no rebuild kits came up. just full replacements. You may need to call a honda dealer.
while your on the phone get a price on a OE unit. C8-)

I am almost certain that your OEM alternator is Denso. You probably just need the brush kit which can be found on Ebay for $10. Get the model number off your unit and search by model number. Honda usually use Denso or Mitsuba and I have never heard of Mitsuba alternator, only starters.

If you can find one in a wrecking yard, it will probably last for years. Why do you need to rebuild a 2008 alternator? High miles?

I’d also look in the phone book under the Automotive categories and see if there is someone near you with a shop that rebuilds starters and alternators – they may be able to supply you with whatever you need (or do it for you). We used to have 2 businesses in this area that did just that kind of work.

Well, there are 3 main components that could go bad in the alternator.
1) worn out brush, can be replaced easily and cheap.
2) regulator, rarely go bad but buy a used OEM one and replace.
3) diodes, if these are bad, it’s best to just hit the JY and look for an old OEM one, the replace the brush then you have a like new alternator.
Make sure your battery is healthy so the alternator can stay healthy.

Also, rebuilding an alternator can be a PITA. I just tried doing my wifes explorer as the bearing went out and it was a 10 dollar fix if I could get it apart.

I got it apart, it more pieces than it was supposed to…it has a remanufactured alternator in it now for $140.

IF you decide to go ahead, my advice in disassembly…remove everything you can down to the basics ( no plastic covers, etc ). Heat up your oven to 400F and put it in there for 10 minutes.

Using a deadblow hammer, wooden hammer or careful tapping with a ball peen hammer, strike the hot alternator around the perimeter lightly to loosen the corrosion. Use a little penetrating oil after the oven if you’d like.

HERE’S THE RUB. Don’t hit it too hard or you’ll end up with a broken alternator. Only tap it around the perimeter to loosen it up. Then take your larger hammer swings on the mounting points which are thicker and can take a few beatings. You are going to try to rotate the two halves back and forth until it comes apart. Don’t forget to have some old winter gloves or something to hold onto the alternator while you are doing this as it will be pretty warm.

DO NOT strike the shaft, you won’t get anywhere with it and you are going to likely damage something in the process.

Good luck.

+1 on the brush kit as that’s usually what is needed. Remans aren’t that expensive and that’s what I would recommend however. Be sure that it’s really having a problem with the alternator as OE alternators don’t often go bad and that seems pre
