I could be the bush/bearing at the base of the column where the shaft goes through the firewall.
And no you cant replace the bush, the only way to fix it is a whole new steering column.:dead: About $300 new from Ford (from memory), or from $10 - $200 from a wrecker
The bush on mine squeaks, I was going to replace it but havnt got around to it, its pretty low on my priority list at the moment.
Oh it could also be the little electrical contacts for the cruise/horn behind the steering wheel, give them a little grease and it may fix it.
