thank you. I will give it a try. it sounds just like what I am experiencing.
Quick ghetto way to get rid of it is to move the steering wheel through it's full travel 30 times or so, and then once every two weeks. So, full out, up, down, in, up, out, down, in...over and over. Helps spread what is left of the grease.
Or, the way I solved it, was by buying some spray on graphite grease. Take the lower kick plate above the footwell out (four screws, three fasteners and unclip the little speaker) and lie on your back in the footwell looking up. Move the wheel up and down, and you'll see a little jackscrew on the left. Spray some grease on that, plus on what looks like a little swash plate and it should go away for good!
Best part of graphite grease is that it doesn't attract more dust and grime.
