    Default Nova/Corsa upper column bearing

    Why change it

    Steering column upper has play but lower does not.

    Parts required

    One upper bearing, part number 90334860



    How to

    Remove the steering wheel/boss and remove the spring.

    Locate the white retaining clips top and bottom and prise them out with a flathead screwdriver.



    They just pop out like this:



    Once the clips are removed, you can twist the switch housing anticlockwise and pull it towards you, see the groove here:



    With it removed, you can see the bearing and washer however it cannot come out from the front:



    These two metal retaining clips need to be removed, simply pull them out with pliers from the front:



    They look like this, with the tab bit sitting inside the bearing groove:



    The bearing is finally held in with plastic springs, so remove them and hold them out the way with a cut up card or similar:



    This gives the bearing a clear route to come out of the rear:



    The bearing just drops out without any force at this point. Important - keep the washer:



    To refit, simply push the new bearing in from behind and allow it to clip into place. Refit the metal clips, careful not to bend them by forcing them in.

    Refit the housing to the column, push back in the white clips.

    Important: Refit the washer and spring, this loads the bearing and keeps it tight.

    How did you find out about the play, Iain ? Do you think it has something to do with the trackdays or just aging ?

    Excessive movement up and down in the wheel was the symptom. Not sure it was to do with track use, I had a wheel boss fitted without the spring and I think that caused it as there's no pressure on the bearing keeping it together.

    Hi Iain,

    Yes that could be the cause. I have always ran mine with the spring.
