Default Decoupler Alternator Pulley Change?

Has anyone done this ? If so how hard was it I was getting an annoying squeak after replacing the idler pulley and noticing it was still their I searched and found that it was the decoupler pulley on the ALT.

I found at least in my neck of the wood s that the pulley runs about $110-125, a whole new alternator runs $159. I figured with the age of the alternator, it may be cost effective to change the whole thing?

It's actually from Autozone or Advance, about the same in price, although it is remanufactered, but that doesn't bother me, mine was 12 years old
