Strange whirring noise from rear
I bought my 2001 V6 Camaro this past July and since then I have been trying to figure out what could be causing an issue I've been having since I bought it. There is a sound that seems to be originating in the rear of the car as I'm moving forward that sounds like a repetitive whir. I've replaced one of the bearings which was bad, but that didn't do anything. The differential is in good shape and I filled it with new fluid, so that's not it either. I just rotated the tires and now I'm looking to replace my brakes soon. I'm thinking it might be a warped rotor at this point, but if anyone else can think of something in the meantime, I'd appreciate it.
