Saturn Aura Steering Symptoms

My Saturn Makes A Loud Noise And You Can Feel The Steering Whell Jerk When Going Into A Deep Curve And Lightly Applying The Brake.

My Power Steering Pump Start Making A Loud Noise. So I Change It Out And The Fluids But Now It's Still Whining.

My Power Steering Fluid Is Leaking Really Bad. I Have To Check It Every Other Day And Put More In. What Is Causing The Leakages And How Much...
