I believe Mopar has a two year warranty on their parts, which is good. Keep your receipt handy! I have had good experience with Mopar remans on CV axle, Starter, and Fuel Injectors.

Was always told on Alternators go with new as the remans never generate the stated AMPs/current under load. May never be an issue for you. Problem occurs when you are at a stop light idling with everything on - lights, wipers, heater fan, window defrosters, and heated seats. At that point, remans do not generate enough current to power all of those loads and keep the engine running so the draw goes to stored power in the battery which is limited.

For that reason, I chose a Remy alternator. Really bothers me because although Remy is a US company the new Alternator has a sticker on it that says made in China. Ughhh...

00RedWJ I've purchased an alternator at advance auto and it was fine. They're rebuilt and will likely be the exact one you have now. Like the last post said, purchase it online and use the code and get 30% off. It will also tell you which store has the part in stock. I live in Long Island and there are a ton of advance and autozones around

achaps81 if you have a advanced auto,*15587

make an account, use the code TRT30 at checkout for 30% off, 121.09, then you have the core charge so it will only cost you just shy of $90

MuloChico You need to disconnect the ground wire on the battery otherwise there is a good possibility of sparks.

It is a fairly easy repair. The lifetime warranty is good, but if it keeps failing the time for repairing it can get old. If you are looking at getting rid of the Jeep, the Duralast will be fine. If you were to be keeping it, I like Napa or O'Reillys. More a personal preference, but I have had some problems with Duralast parts.

optdoug I son't think there is anything wrong with the Duralast alternator's from Auto Zone. I bought one for mine a few months ago and it works just fine. And I think there was a lifetime warranty on it as well. So if it fails, I can hopefully just get another one.

As far as the 4.7 engine goes, I'm not sure how easy it is to replace. But I have a 5.7 and it wasn't too hard at all. I just removed the serpentine belt, air box, radiator reservoir and upper radiator hose. Then remove the two bolts on the alternator and twist and turn the alternator until it worked it's way out. Install the new one and reattach everything. It took me maybe an hour to do. The only thing that stumped me for a while was loosening the serpentine belt. Once I figured out you just stick a 3/8" ratchet in the square hole on the tensioner pulley, it was all good.

Need New Alternator. Model Recs for '05 v8 4.7L?


For starters, I don't know much about fixing my own car. I live in NYC and don't have a garage. Anyway, I had a battery issue today and was advised by the shop I need an alternator, too. He was going to replace with a Duralast Gold for $240 plus $98 labor, but I held off. I looked up the brand and found it on sale through Autozone for $191, at the very least, saving $50. But then I started reading about AZ parts and all the problems people have with them, including Duralast alternators, so I thought I'd check this forum for advice on buying a different brand to put in the car instead.

I don't drive much, the 2005 Jeep Grand Cherokee Limited v8 4.7c has about 90K miles, and I hope to sell it in the next year, so not looking for the most expensive, heavy duty option. Would like a part I could buy online and have my regular mechanic install. He was closed today due to the holiday.

Thank you in advance for the advice.
