Squealing noise at low idle in drive or park
Hey guys!
I have the Alpha 5.3L V8. I been getting alot of squealing from underneath the car at low idle in park and in drive. Anybody else got this problem. I had it into the dealer 3 times and they can't find out what's causing it. I thought it might be the alternator but it sounds like it's coming from below like in the center of the vehicle. Any help would be greatly appreciated!!!

If it is a belt squeal then it is the alternator. Educate your "dealer", there was a TSB on this topic. Go search it out.
Basically the resolution is to replace the alternator. The noise is cause by a poor alignment of the alternator pulley to the S belt.

Ok thanks for the info! I did notice some black power coming out from the inside of the alternator. Wife said when she's driving it at night the lights are dimming as well. I think I'll replace the alternator and the serpentine belt and see if that takes care of it. Vehicle only has 38k miles on it.

My warranty expired last week. When I take it in there it's not making any noises but when it get's hot it squeals like a little pig. When you give it gas noise goes away. Anyway the guy at the dealership said he will try to get it covered because it was an existing problem from before so we'll see. I called the guy at Autozone and he said they can test it tonight so I'll know if it's shot. My question is that if the system is low on voltage supply can it make other systems malfunction and squeal? Because is sounds like the sound is coming from by the transfer case/transmission area or something.

I gotta get some updated pics on here because for her birthday I got her roof racks, a chrome hood grille & the aluminum gas cap. These were all authentic Hummer accessories.
