Hey everyone. I have a squealing noise in my 2003 g35. It starts at 2000 rpm and stops at about 2300. I've replaced the belts and that wasn't it. It sounds like metal. Bearing maybe? Any help would be great.

 

Probably one of the idler pulleys (tensioners). You might try the redneck stethoscope to isolate which one, (a piece of heater hose, garden hose etc. 1~2 feet long). Put one end in your ear, the other near the suspected noise source.

 

I had my looked at by a friend that works for a the Nissan dealer where I bought my car, it's the drivers side bearing. He ordered it at his price about $160. Another $100 to install. It's getting done this weekend.

 

So tanko yours only made noise running at certain rpms? Was it the tensioner bearing? Thanks for the info

 

$160...wtf. Is this the price for the idler pulley on the drivers side?

 

Yes, mine starts the whining noice around 35-40 MPH. Below that I dont really hear it.
$160 is for wheel bearing.
