Have you sprayed WD40 at the top bearing area and the bottom bearing, next to sector gear, to see if the squeak goes away? If it does, get some silicon spray and use it on a regular bases. ?
I cant hear the squeak, so I have to go by what you say. If the noise is in the column, the oil should quieten it don for a shirt time. If not, tells me, that is not the squeak source.
If noise is at the bottom of the column, you can't get oil or grease to it. You would have to take out the upper bearing or remove the shaft from the outer cover to have any chance to lube it. I will send to moderator for refund.
