[urq] Rear hub dimensions

[Gary Brown]

Hey all:
 Does someone here have access to the dimensions of the rear wheel hubs on the urq?
 
Specifically the part that resides in the inner wheel bearing.
Reason is, I'm getting a clunking. 

 With the right rear wheel off the ground and holding it at 6 and 12, I can feel it move. 

Wheel bearings are brand new. 

I've been told it can be that the hub has tapered from the inside to the outside, and also it could be the bearing is moving around between the clips.

TIA
Gary
