Hi All I have found that the noise is louder in cold conditions, less noticable in hot conditions, therefore the 'lube' is harder when cold and softer when hot, also I have degreased around the top of the steering rack where the shaft goes into it, there is a seal in this area that I am told was replaced on some vehicles under warranty, but takes a long time to replace, i.e. the steering rack has to come out, try degeasing around this area, then when dry, lubricate slightly, this worked for me Regards Bruce
