Barn bird , All good points, I should also have mentioned all new belts and completely replaced all ball joints, tie rod ends and had a front end alignment. I did all this because the steering seemed to drift both to the right and left , more noticeable at 40-60 mph. This work did not help the steering drift. Also never affected the pump noise. The squealing is from the pump as I stated and fluid level is right on the full mark. New tires may have 1500 miles on them. Steering box was checked during alignment and was tight, no slop. U r right on turning steering fully right or left for the squealing . A that’s just what it sounds like only it’s not fully turned. It’ll squeal from straight forward to fully turned right
