My front end is squeaking

A couple of things. It might be nice to know the model year and how many miles.

Most bearings and suspension components are sealed. It rarely works to spary lub as the lub can not get into the areas needed.

Does it make a difference if turning while moving? If the noise is worse turing right, think the left wheel bearings. Right turn, left bearings.

Also, try turning the wheel near the limits of travel. If it squeaks at the last 1/2" of travel, think steering rack support bushings. Depending on the MY, there is a Ford TSB on the problem.

Ball joints are a possibility.

Squeaks

I had the same thing on my GT. The rack bushings had shrunk and gotten hard. You can replace them without removing the rack. Just pull one rack bolt out at a time. There is room to get the new bushings in and re-instals the bolt, then repeat on the other side. I replaced mine in about 30 minutes. Stopped the squeaks and got rid of the steering wanders. I put some poly bushings in mine. Really improved the steering feel.
