Hi, I have seen a post here months ago, about how to grease the spindle bearings on an SX3, but cannot seem to find it now.

My spindle is rather noisy, and I would like to try and grease the bearings in the hope that the DB count will come down dramatically.

Can anyone explain how to do this?
Is this a 2 hour job, or a two week job?
Is the quill spring tricky?
