Squeaky steering

[Tom023]

The steering rack/coupling started to squeak this weekend on my 2001 X30. Steers fine and is not binding, just starting to make some noise. A quick check and I could not find a grease fitting anywhere on the rack or steering wheel shaft. Has anyone ever had this problem or lubricated these parts?

I think the rack itself is sealed so there would be no grease fitting. The only fittings I know of are on the cable.
