Di Base Responsive No Matter What I Do?

Hey Guys, I’m trying to get this Di Base unresponsive for a friend of mine. It seems like no matter what I do the bearing goes responsive after a few hours of play. I’ve changed the bearing now about 3-4 times.

Any ideas guys?

The one I have does not do that.
So your sure its not the bearing that died?
Considering you switched 3-4 Times i suppose not.
Maybe the bearing seat or Maybe because of the Pads?
No other ideas Sorry

Check if something is in the bearing seat. Types of bearings can also have an effect. Try a YYJ Speed Bearing. I used to have this problem all the time until I started to keep the shields on my bearings.
