2007 Ford F150 - It's a little off center

replaced both high and low pressure lines on the rack on my 07 F150 4x4 after my steering wheel was a few degrees off to the left. short time later started hearing a whining at higher speeds now a couple wks later it has gotten load, thought it might be air in pump any suggestions. thanks dave

That is not what fixes an off center steering. Are you sure you connected the lines properly? And any air that got into the pump was purged within a few miles of driving if you didn’t purge it before you drove off.

What is “gotten load” ? I have no idea what this means.
