Left turns and sometimes right turns, grinding noise

if you hear grinding noise while driving, it usually comes from your brake or tires touches fender liner, if noise remains constantly, may be from a pulley bearing.
For your case, check front tires, turn it right and left to the max, check if it touches anything; if not, check the brake, a nearly worn pad will expose its metal part, it will contact the rotor and makes noise.

It could be worn out constant velocity joints, if it is noisy only at slow speeds, and turning makes it happen too, get them checked asap.

Most likely one of the drives or cv joints

Sounds like wheel bearing, an easy way to check it out is to just jack up that corner enough to get the weight off the wheel then with one hand on the top and one on the bottom of your tire check for any play. If there is play your bearing is bad. the play will most likely be very very little (less than 1/16 of an inch) but there should none whatsoever. if the grinding noise happens when turning left, check the right side or grinding when turning right check the left side. sometimes the bearing has a bad seal or wasn't properly lubed when being made.

CV joint on the left side is going out. It will grind once or twice "sometimes" when first starting to drive. Best to have both CV joints replaced. Roughly 400.00 to 450.00 parts and labor. Don't take it to a dealer. Dealer shop rates run 90.00 an hour. It will instantly become a 700.00 to 800.00 dollar job. A good reputable mechanic can order replacements and have it done in a day!

Check the brake system of front right wheel. I am sure, the problem is there only.

Need more info but sounds like power steering gearbox or cv joints. What happens when you turn all the way left or right? Is it worst or better and what do the noises sound like? Whining or grinding?

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.

check that you havent bent the baking plate behind rotor or drum that it is just touching the disc rotor and any anti rattle clips on brake caliper that they are fitted correctly.

the grinding grating rattling annoying sound is yor axles (velocity joint) it could be a simple thing as the boot rubber poping out and the grease spilled off or the bearing is shelling. In any case have the joint repaired or replaced. After this you will need to align as the changing or removing of the joint messes the alignment up.
