C5 Steering Column noise

[tonyg]

At low speed when I turn the wheel I get a noise just under the steering wheel like something is rubbing and needs lubricating. I suppose you could call it a squeak but it's not high pitched, more like a muffled groan. I have not yet had a good look but was wondering if anyone has had the same and how you fixed it.

Where the steering column shaft goes through the firewall there is usually a nylon bush. This groans when it gets dry. I've tried spraying Silicon or PTFE up in there but its quite hard to get to the bush itself with everything else in the way.

I find its temperature and weather dependant. Mine groans most on dry hot days.

I usually either drive faster or turn up the stereo.
