I have a 2003 ALH with 390k km on it. A few days ago I started hearing a whirring when the rpms where up. The sound is in sync with rpms so I don't think it's the turbo, it's gotten progressively louder and more pronounced over the past few days. It kinda sounds like it's in the area of the IP/PSP/Alternator.
The best way I can describe the sound is like a transmission when driving in reverse.
I'm thinking Power Steering Pump but I'm unsure how to take the belt off the accessory drive quickly to just test that.
Any input would be greatly appreciated!
