Hey guys a couple of days ago my power steering started making noise when I would turn the steering wheel left or right. The fluid in the reservoir looked like it was full of air ie. very foamy. I put more fluid in and today jacked front of car up and turned wheels lock to lock at least 20 times. There was no noise. Put the car back on the ground and there is noise when steering again. Any ideas what may be causing this? The noise sounds like low fluid or air in the lines but the fluid isn’t low. Isn’t the bleeding procedure to simply turn wheel lock to lock several times?
