I bought two to replace both rear wheel bearings on a 2000 Dodge Neon. Size and fit were perfect. The bearings appeared to be adequately lubricated by the packaging. It comes with a new axle nut which is a nice touch. Unfortunately, one of the two I bought makes very little noise when braking. I can live with it now and it's certainly better than the rusty worn junk I got out of the car, but I expect the noise will get worse over time.
