Brilliant bit of info. My local dealer is totally uncooperative so I'm going to do this tomorrow with CV joint grease. I'll let you know how it goes.

Done it. Very easily done. Greased the knuckle joint under the cover and also the splined one around a foot up the shaft. Knocking gone and much more responsive steering.

Only problem to watch out for is that my steering wheel is not straight now.
