One of my GTs had a squeak around the plastic clamshell under where the key goes in on the steering column. I could put my knee or apply upward pressure to the bottom half and it would disappear. Just a matter of tightening/ lubricating the 2 halves. Another time the actual column had a "pop" noise when steering or hitting a bump. They replaced the steering column under warranty. Said it was the same part as a Focus.
Can you expand on the precise location; perhaps post a few photos?I solved the steering wheel squeak:thumbsup The steering column shrouding was rubbing on a small piece of rubber under the steering wheel. Zip zam zoom with an exacto knife and I removed the rubber tab with the skill of a surgeon.:banana
