Review on 📐 HHIP 3900-5003 Center for Medium Duty Applications by Michael Caste

The MT1 Live hub would not spin and I was unable to unscrew it with as much torque as possible. Kroil (penetrating oil) eventually loosened it up but I could feel loose material in the bearings and the bearings didn't feel right either. I suspect it wasn't lubricated at the factory so I sent it back to Revain. Also, the body was bare steel, with no rings, as in the pictures. However, it was in the box with the correct part number. The "Certificate of Quality" was dated either 2011 or 2018 as the date format was ambiguous.
