This due to either a worn wheel bearing or a worn front drive arm.
The most common cause of a grinding noise when turning is a worn front wheel bearing. What happens is that the weight of the car is shifted on to that wheel as you make the turn causing the worn bearing to make a grinding noise.
it can be any part of the front suspension or brake system including drive train damage jack up right side and with wheel still on place hands at top and bottom of wheel and push and pull in and out if movement usually a ball joint but ball joints dont give off a grinding noise ===now grab tire at the 9 and 3 position front and back -push and pull if loose possible tie rod damage or steering component damaged this also doesnt give off a grinding noise unless bent into a turning part =====turn wheel and listen and look at cv axle and around brake area if noise remove wheel and now inspect brake caliper ,brakes ,hub and axle for noise these components can give you your grinding noise repair or replace damaged components the other tests performed were for possible damaged parts since wheel was bent inward
most likely a front hub [wheel bearing ]going bad but jack up front side that is causing problem and try to move tire in and out with hands at top and bottom of tire and listen and feel for noise or excess movement it to much movement remove tire an check the upper and lower ball joints as well as the shock/strut but check brakes grinding can also mean pads are metal to rotor but usually grinding and thumping is related to a bad hub
Grinding is a sign on brakes in need of replacement. Your pads are worn through and now the metal backing plate of the pad is grinding up against the rotor. Replace the pads and rotors asap to prevent further damage.
If you still think the noise is coming from the left side CV joint it would be more advisable to replace the entire axle as an assembly. For the time and effort it takes, you can usually get a rebuilt axle assembly for only a few dollars more than the CV joint and the boot required to repair one. You will need a large axle nut socket (usually 30 - 32mm) to remove the axle nut. The lower ball joint and tie rod will need to be separated along with the brake caliper and rotor, from the spindle. I would recheck the grinding noise before doing it. A lot of wheel bearings are mistakenly diagnosed to the wrong side. If the noise is loudest when turning left, most people would assume the left side wheel bearing is at fault. However if the noise is loudest turning left it indicates the right side wheel bearing is most likely at fault. Due to the weight distribution of the front end, turning left the weight all transfers to the right side, loading that bearing. Make sure thats not the case before tackling an axle.
Watch out! You might have a loose wheel! Check those wheel nuts. If not, a loose brake caliper, or last if not least, a bad wheel bearing. Don't drive it until you find out what the heck is wrong! Could be dangerous.
3 things to check:
Worn disc brake pads, grinding against the rotor.
You posted grinding gets worse turning to the right, the problem is the driver side wheel, but it would be best to have both wheeles checked.
You can see the brake disc on the front wheels, Check both sides of each side, looking for scoring. Brake pads have wear insicators on them that are metal tabs that contact the rotor (disc) when pads get thin. It would be better to pull the wheels off to get a good look at the pads. Good luck
grinding on front wheel is caused by 2 things.
a bad or loose wheel bearing,or worn out brakes, have them both checked
You might also want to check the level of fluid in the power steering
reservoir - low or lack of fluid will also cause a noise (although more of a
whining than a grinding).
