Post up a link to your new post here also and we will get a heads up about such.
Also maybe a video of the you are hearing.
Back side of belt scuffed can also be a flat idler not spinning good.
Belt will get hot and a new belt might have a slight chip or belt scream when belt is cold and tone change as belt heats.
Might have to get someone to watch the belt when it operating. STAY SAFE.
See if it's jumping or vibrating. Ringing sound is usually a dry bearing and I've seen lots of NEW spindles now days that new bearings are dry, no grease.
Also let it operate little while and then kill the engine and feel of the belt and see if it's hot. If the belt is not hot it's probably a spindle bearing and most likely a upper one.
