Installation: The lower bearing must be handled with great care - it is internally angular contact which does rely on the inner and outer races to have the play 'dialed out'. To achieve this, the races are pressed together and can easily separate when removing fork (which if not careful, can result in the ball bearings falling out). There is no alternative design/construction option for this bearing. We cannot be held liable in future, if mishandling or bad installation results in races separating.
