So pretty much Every time I make a hard turn, say driving around a roundabout, I'll get a whirring/howling type noise coming from the front. It happens both when making a left and right turn. I know I need to replace my rotors and pads and haven't had my rear differential fluid changed yet but not sure if this can be the cause. Any ideas? I'll try and get a video of it tomorrow.

 

Check your power steering fluid level and power steering v-belt might be loose.

 

Do not lock your wheels and you won't be stressing the power steering system. It is never a good idea to turn the wheel until it stops on any power steering system. It is called deadheading the cylinder and rack and pinions just aren't designed for that kind of abuse.

 

Power steering fluid is good. I flushed it out about 6 months ago. No bubbling or anything either. I haven't checked the belt yet but I'll take a look. And it's not so much as turning it all the way til it locks it's just turning it 90-180 degrees either way I'll get the sound. Like backing out of my driveway n turning out I'll hear it. Or turning into my driveway I'll hear it, as far as driving on freeway n making right or left turns no sound.

 

Are you sure it is not your transmission? Post a video.

 

Could be your wheel bearings too. They make a howling/whirling noise when they're about to go out....
