suspension whine?

[SHOemup]

Today my car made this noise. Kinda like a high pitched hum. It made it a few times. Mostly when I was starting from a stop or rolling forward a little. Any idea. Something need to be greased? Thanks in advance

Is the noise coming from the rear? Sounds like the noise the rear brakes make when a caliper is hanging up slightly.

My car makes the same humming noise. It sounds like it's coming from under the hood, and when I hit the gas, it stops. I have no idea what it is.

it is coming from the rear but it's loud. I dont think it's a caliper hanging up but It could be. thanks for the help. anyone with other ideas please add on!
