Wheel bearing?
The best test is to push and pull on the left and right sides in an in and out way, and if they are sloppy or loose while the steering is locked, then they need to be changed.
Even with 130k miles, what chews up f-body front hubs a lot (but not always) is bigger tires, like a 315 or so and if you drive hard like autocross or track days with the bigger tire, it stresses the hub. If it's like a 275 or smaller and you don't autocross or track it, 130k doesn't always mean you need to change it.

Used bearings will be audible when you spin them by hand. Thats normal.
The telltale signs of a bad hub bearing are measureable play in the bearing or noise while driving. Typically a bad hub will make a "whop whop whop" or rumbling noise, and the noise will become more apparent when you turn in the opposite direction of the side that the bearing is bad on.
