So for alittle while now i've had a weird noise coming from my rear right wheel. At first I though it was the brakes sticking so I disassembled and lubed everything up. Still faintly made the noise though. Today I took the car out after not driving it for awhile (my father took it a couple times out though) and the noise is extremely loud. Applying the brakes now doesn't change the pitch at all. So what am I looking at, wheel bearing gone bad?
