I'm looking for the name of a part in the steering column of a 2011 Ford F150 4WD 3.7 Liter. The part goes through the firewall to allow passage of the steering column. The part is squeaking up a storm and it is driving me and the wife crazy. At first I thought it was the clock spring, so I took that out and it was bone dry, no grease. I put some white lith in it, but the noise continued. I did further disassembly and could feel the steering column squeaking and traced it to the firewall feed through.
Has anyone replaced this item? It doesn't look too difficult but the steering column will have to soak overnight to allow disassembly.

Thanks for any input.....

 

Likely - Dash boot bearing
