Jack, with housing stationary and wheels rotated, we did see a bit of fluctuation of about +/- .005 to .010, but it was rather sporadic and not relative to the welded pads. When the tires where stationary and the housing was rotated around, before our heating efforts the runout started at about +/- .050, and was directly related to the welded pad location. At the point the housing was being rotated, the dial indicator remained in the same spot on the wheel, so although the wheel isn't perfect, the reading should have reflected housing issues only.
