The OEM wheel bearings are great . After installing the bearings with the after market hubs..I had a vibration. Soon after my brakes started making rubbing noise. I thought it was my rotors being out of round so i machined them. Vibration was still there and so was the noise. After further inspection.. It was the front hubs that are out of round. Contacted them thru here but after two weeks.. Haven't heard from them. Tried calling but no one picked up and their voice box was full so i couldn't leave a message. Have to replace the bearings again and use OEM hubs.
