3g Upgrade for Les$
Moderator: This would make a good sticky. Or an addition to your tech link section. Thanks.
If you're thinking about doing the 3g upgrade, or you've already done it, the following post could save you quite a bit of money $$.
A few years back I did the 3g upgrade on my truck. I am happy with it.
But my j/y alternator lasted 3 years. No problem. I had a spare j/y 3g. That one died in two months! A.Zone wanted $190 for a rebuilt, plus a core!
So ... I started looking around.
I found an excellent vid on youtube, that was professional and helpful:
Through the vid producers' site, I found I could buy a rebuild kit, for a 3g, complete with bearings, voltage regulator, brushes and housing, slip collar, for only $29.32. That is quite a difference from $180 at A.Zone!
https://alternatorstarterrebuildkits.com/product/3g/
They also sell kits to boost the output of your alt. 40-50 amps.
I think the smart way to do the 3g upgrade is to pull a j/y alt, and rebuild it using the kit. That way you know it will last. The trouble I've found with buying one already rebuilt, is that they only replace the parts that are broken, not the ones that could fail in a few months.
