My 2003 saturn vue makes squealing sound at the

Sounds like your serpentine belt. I would check the condition of your belt on the engine. It is possible that you could also have power steering pump issues. Check belt condition first, Second if the belt is not glazed and looks ok remove the belt and check movement on power steering pump pulley to see what what type of resistence is presen while turning pulley. If so, pump should be replaced. This could be causing belt to slip and make the squeeling that you are hearing. If no resistence on pump replace belt and varify repair. Good luck.....
