i think it has to do something with your arm shaft rods , because i do believe your tire bearings are fried or torn
Interesting terms in the first response. What kind of car? Could be as simple as the tire rubbing the inner fender. Backer plate on the brakes rubbing the rotor. Only when turning? Either direction?
I'd try changing tires, worked for me.
bad rack and pinion
The grinding is a worn CV joint. Get it replaced before it causes more damage! A worn wheel bearing will make the same noise answer worn wheel bearings or worn brake pads will be the cause
Warped rotor and worn out brake pads.
Maybe tirod end or ball joint Check strut bearings.
tie rods
Are the breaks worn or have they been recently replaced and could need new rotor. check your wheel bearing as well. turning left puts more stress on the right side of the vehicle, this could cause the grinding noise.
broken motor mount(s)
It sounds like you have a bad CV joint. Often times the rubber boot covering the joint will go bad after a while and allow dirt and moisture in the joint, causing noise, most noticeable on turning.
the gear box may be going out or its metal on metal rubing somewhere
It depends on where the grinding noise is coming from. Most of the time the grinding is coming from the brakes and the brake pads need to be replaced. If they've been grinding for a while, the rotors will need to be resurfaced or replaced. Other possibilities for grinding are worn axle bearings, or a problem with the clutch. If the clutch goes out, there will be a grinding noise when you try to shift gears.
Its usually a U joint. Click under acceleration . While turning,a CV joint. Grinding or moaning is usually a bearing.
