03 c5z making oscillating roaring noise from what sounds like the left rear and gets more prominent with speed. Just from the noise of it I could’ve swore it was a wheel bearing but just changed it with no luck. Any ideas? Could these old shitty proxes be making noise? Attached video of said noise.

In my experience, r888's made my car sound like my rear wheel bearings or diff was going out with a loud humming/groaning type sound

Yes! Had the exact same noise with some 5 year old, but never used R888s when I finally mounted them.
