Alternator Replacement with Pics for 4.4 M62 V8 (rebuilt)

[princemoe2m]

I finally got the X back on the road after i replaced the alternator, upper timing gasket and VANO gasket replaced as well... while i was driving back home the battery light kept on coming on and off.. mostly when i had the heat running and turning singles when am turning or taking off from a red light. when i checked the alternator Voltage at the shop befor i left it was reading 14v(green mark).
anyways i thought it would go away, but after i left school this evening i noticed while driving my headlights get brighter and dimmer while am looking straight at the road
so when i got home and did a search on how to check the battery voltage. i got the reading from the cluster at 12.2volts while the truck was off. is that the right voltage it should be at? or i have replaced a bad alternator? does anyone had this before? i would appreciate ur feedbacks

Start the truck and the battery voltage DROPPED to 11V, and would not increase as I revved the engine

I left the truck there while I sourced a new alternator.

Dealer list $950.00

WOW! At those prices, I was now fully prepared to take the thing apart myself or take it an old alternator shop in town and try my luck.

Anyway, some internet searching led me to novastarparts.com They rebuild alternators and starters in bulk for emergency fleet vehicles and others.

Price CANNOT be beat: $171.45 !!!

Hello there I went to this website and it just directs me to other sites and cant find an alternator for near that price do you have a direct link or can you direct me? thanks

Hey Storm...welcome to the forums. Now, if you'd actually read the entire thread, it's been noted that the alternator site has been closed and a replacement hasn't been found. Maybe you should start searching around and find something, then post it here for others.

I replaced mine in February, I found the best price at NAPA. They have NAPA rebuilt for around 260, Bosch rebuilt around 500. I went with the NAPA rebuilt, obviously the core is the same.

Hey when I run the engine the computer tells me the voltage is about 10v can this be the regulator in the alternator that needs to be replaced or can it be something else.

Completed the alternator replacement last week and this thread was a great help. Thanks deville. Hardest part was getting the fan off and I know its a reverse thread. Just took time to remove all the stuff out of the way.

So if you have basic mechanical skill you can feel confident you can do this and save a ton of money.

I used a reman alternator from Eagle electric because it was cheap and close by so I could pick it up. Paid $235 and got back $50 for the core so total was $185.

Redline....keep us posted on how that alternator does. I"m curious if they've got a solid reputation for rebuilding, or if it's got a limited life.
Thanks!

I will keep everyone posted on the performance and lifespan of this alternator.

Everything is great after 2 months with the rebuilt alternator.

Help I changed the alt with my original rebuilt and the water pump while I was there. Now the engine cranks and sometimes starts but when it does it idles rough with no power and finally cuts off. What can be the problem?? I made sure all hoses and connections are fine.
