Sound Near Alternator in Toyota Premio 260 (2013)

[RevTalk]

Hi everyone,

I own a Toyota Premio 260 (2013), and recently, I noticed a strange sound coming from the alternator area.

Here's what has been done so far:

1. A mechanic suggested that the alternator bearings were worn out, so I had them replaced. Unfortunately, the sound persisted.
2. I then replaced the belt adjuster, but the issue still remains unresolved.

Has anyone experienced a similar problem? If so, what was the solution?

Any insights or suggestions would be greatly appreciated!

Thanks in advance!

Could be the AC compressor, if you can post a video that'd help
