Contour Enthusiasts Group Archives Forums Modifications General Mods New Power Steering fluid, new noise

I had valvoline synthetic fluid put in my 98.5 v6ATX. It had air in it and would make a noise coming from inside the engine bay. That went away after working it out. Now the steering wheel inside the cabin makes a sound when it is turned. Its not loud, just it used to be silent. Any ideas?

Thanks
