A minor play in the direction of the spindle is normal and prevents the left industrial bearing from exzessive play in axial direction.

After assembly (before being installed) the unit has 0.1 up to 0.2 mm of axial play. After tightening with 140 Nm, this play mostly disappears.

Important: This play can't be adjusted and is not disadvantageous at all for a proper function.
