Its showing as part number 3C662 in my ford repair manuel and I can't seem to find it anywhere. While I was doing some other work in the area I noticed there is play in the lower u-join on the lower steering shaft, it doesn't look user replaceable.

 

It looks like the full part number is F69Z3B676FA, still haven't found anyone who has it or a replacement though.

 

I am also showing a F29Z-3B676-A, as an older number, but nothing in the wild that I see.
