Sounds like the lower steering shaft U-joints are bad...somewhat common problem. Go here: https://www.f150online.com/forums/ar...t-04-08-a.html

 

With the engine warmed-up, pull the cap off the reservoir; if you see champagne bubbles, you have air in the system. To work air out, slowly go from lock to lock (with steering wheel) and air should gradually work out of the system.

 

gearman do I leave the cap off resv while turning lock to lock if there is bubbles

 

Yes, Leave the cap off while working any air out of the P/S System.
