Hello everyone, I replaced the rear shoes (Hyundai parts) on our 99 Elantra GL this past August. About a month ago I started to hear a swooshing sound while the car was in motion. I had a look at them a few days ago trying to play around to figure what was wrong. I took the drum and placed it half way in and rotated the hub. This is where it was making the noise. The car has about 110k miles, does it appear that I need to replace the drums? What else could be the problem? Thanks in Advance, Nick
