Thats Great. They finally pulled my stock hub out. It looked 99.9% perfect. (Not damaged at all like the other guys one in his pic.)

At best there was a fine line around it. Pretty much all looked new. However we are replacing with brand new factory parts, and will loctite the bolt and use higher torque. There was no damage at all. But replacing all parts just to be safe.
