For about 8 months or so I have had this whine that sounded like a supercharger. I didnt try to fix it b/c it wasnt causing any problems and it sounded pretty cool. Well yesterday i decided to figure out what it was. I thought it was the alternator so i pulled the belt, cranked it up and it still whined!! So it ended up being the idler pulley for the ac. $40 fix for the assembly now its so quiet its like driving a different truck.

For those who didnt hear it this is just how loud it was.

What was the part number you got. Mine is whining too!!

 

il look when i get home, i got it from o'reilleys. Its the whole assembly not just the pulley, it would be too easy just to replace that.

WHEN I FIRST SAW THIS POST I THOUGHT MAYBE YOU JUST REALIZED YOUR OLD LADY WAS IN THE TRUCK

IM AT WORK AMN... AND ALL THE DAMN FILTERING THEY HAVE I CANT LOOK AT NOTHIN.... HELL HALF THE PICS PEOPLE PUT IN THEIR POSTS WONT EVEN APPEAR

WORK FILTER =

 

il put it this way, standing in front of the truck with the hood closed you couldnt hear the exhaust for it. I never realized how loud it really was unitl today when i got to drive it a lot.

 

I replaced my ac idler a few years ago for a noise also...mine was only noisy when the ac compressor engaged though, it sounded like a jack hammer. It was super easy if I remember correctly...like 2 13mm bolts or something, and it's done. Also had my main idler pulley replaced under warranty, it was squealing like a pig.
