Noise from the rear

[4ofus]

So, a few months ago I started noticing more noise than usual from what I think is the rear tires, just sounded like the tires were wearing funny and starting to sound like truck tires, I changed the rear diff fluid with some good Redline stuff and the fluid that came out did not look bad and was only a tiny bit low. The noise was still the same so I put a new set of rear tires on it and the noise is about the same. What do you guys think it might be? Wheel brgs?

I think your on the right path with wheel bearings.
