Ordered new rotor, with integrated Hub, but it arrived damaged (there was a broken magnet). I was able to use the new hub on my old rotor (3 bolts attach it, but you can't buy just the Hub). Started Chat session with Appliance Parts Pro today and they issued a replacement and 20% off next order, plus the shipping - it was painless. Replacement is a breeze. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
