Power steering pump
Have you done some intense parallel parking lately?
Sometimes caused by a lot of parking maneuvering. Pump gets hot, fluid reaches it's boiling point, air gets into system.
The older the fluid, the more likely.
My "Alldata" info suggests putting the front end up on blocks to limit resistance.
Turn the wheel very slowly, both directions multiple times, changing directions before reaching the stops. Hitting the stops is a no-no. That's when problem develop.
I''ve done this 3 times w/ 3 different Ford vehicles. Worked 2 out of 3 times.
I also changed fluid, adding new before the procedure.




and I can feel tiny vibration on the wheel when i turn.
