I bought two of these for my 2001 Nissan Altima GXE rear brakes. After putting these drums on on a test drive, I heard a sort of "digging" noise from the right rear end, but this noise only occurs when I apply the brake to stop/slow the car. So I tried replacing the rear right drum with the old one and then no sound. So now Revain is shipping a replacement. I will update the post after receiving and testing the replacement.
