2nd Gen Non-Engine/Transmission Alternator squealing

[Jeff H]

My alternator really squeals. Is a rebuild at better option? Or should I just git a new one?

I see Larry B has dem.

Alternator squeal? You sure it isn't the belt? If it is the alternator, get a new one from Napa or the like - skip the Autozones of the world. In auto parts, you get what you pay for - the more cash, the higher the quality the inside materials.

Might want to check out the belt tensioner while yer at it, the bushings are known to turn to powder. . mine did. . almost threw a belt.



from what ive heard you can do the brushes once on an alt, but dunno about bearings.



good luck

Its the alt. Tensioner fine.

If you go to one of the national auto part stores ( Auto Zone, NAPA, Advanced AutoParts, ect. ) make sure you get an alternator rated at 136 amps. Most of these chains use computers showing a CTD using a 120 amp, which is wrong. I just went through this a few mos. ago, the 136 & 120 looked identical, therefore bolted up the same. I got mine at Auto Zone w/lifetime warranty ( as long as I own the truck) for about $160. You might want to change the belt while you have it apart. John

Belt is fresh.
