O8 Sierra rattling/jingle noise front end

[Mnr1987]

Hi guys. I got a 08 sierra with 100k on it. Been noticing a jingling/rattling noise in my front end. I believe it's one of the pulleys or ac compressor.....anyone else have this problem? It almost sounds like a bell jingle. Does it on and off no rhyme or reason.

have you ever changed a belt tensioner on it

[Mnr1987]

I have not. I think I will take the serpentine belt off this weekend. Should be easy to diagnose which pulley is bad I would think? Might as well put a new belt on it to?

change tensioners also

I had this same thing going on in my 09 Silverado. But I think it went away, it sounded like on my truck it was coming from the front left tire area. A few weeks back I went and rotated my tires and had my broken leaf spring fixed and the jingle went away. I will add that the brakes are smoked on the front. Only had 78k on it when I checked em, not really sure if thats normal, but after having the tires swapped around the noise has gone away.
