hey guys!
one again i would like to thank everyone in advance for all the help till this date!
so, i have this noise which kind of sounds like the power steering pump, but that was replaced like 30k miles ago so i doubt its that but it sounds similar to that of the pump. it happens from a complete stop making a left turn from my parking lot , there is a slight decline from the lot to the street. so a left turn with all the weight on the passenger front side results in a slight grinding noise. when turning on level surfaces left or right i cannot replicate the sound. any ideas? i was on benz world and some people are saying a rusty caliper? or bushings on the lower control arms? or bad engine mount/fan shroud?
please help me end my wandering thoughts!

 

I would check the wheel bearing and the brake pads and caliper.

 

You know it is tough to say without actually hearing it. Are you sure you don't have a tire rubbing in the wheel well? I have never heard my OEM size tires rub, but when I take my wheels off the car, there is evidence on both sides of the car of the tires rubbing in two areas of the wheel housing inner fenders.

We have a 2004 Automatic and had grinding noise when wheels were turned to left only when backing out of driveway over small hill. Turned out to be the front left tire scrubbing the wheel well when the shock was depressed just so when backing out of the driveway. Some of the undercarriage on the passenger side just below the wheel well came too close to Mother earth apparently (no one will confess to this) and bent the upper part of the wheel well in just the fraction needed to make it scrub.
