Easy to do, even with engine in.
Just move bottom part of column out of the way by removing column or sliding lower part up the sleeve, then take plastic part of the end, then prise out centre plastic piece of bush from the rubber outer in bulkhead, then remove rubber piece.
Re install in reverse order, making sure inner plastic piece of shaft is pushed fully into plastic piece within the rubber outer in bulkhead, then push the CLIP down to hold in position.
