Is It The Abs Pump?

[ottoman]

I have a 99 silverado. It has been making this squeeking noise for about 3yrs now it goes away when it gets warm. But I have, or I think I have traced it to the abs pump. Whenever it makes the noise you can feel it kinda vibrating through the lines by the pump. So. Have any of you ever heard of this? if so whats the fix? Thanks for your time.

just unplug it and see if it makes the same noise ,
