Vibration/Humming/Grinding noises when stopping or turning left.

Check the wheel bearing. If over or under torqued, it may give problems. Check the drive shaft is not bent from hitting a large stone whilst moving.

Struts would not cause vibration problems, A CV joint could, turn your vehicle in a parking lot hard right, make a circle than turn left make a circle ,if you hear a noises you have a cv joint problem. If you feel vibration on the steering wheel its in the front, if you feel it in the seat its in the rear.
Tires out of round & Balance very common as well brake rotors cause vibrations.

Any wear or play in a bush or rod usually gives a 'knock' or causes vibration, not a humming noise.
If there's play in the steering wheel that may be due to a worn steering rack and pinion.

A worn ball joint can cause a 'crack' noise and depending on the wear, vibration that will be felt through the steering wheel. A worn ball joint can also cause the car to pull to one side.

A humming noise suggests it is either a brake rotor/pad, or a worn driveshaft or wheel bearing.

Is it more like a vibration and humming, than grinding noise? If so it would be a bad engine or transmission mount. To check bearings while driving.. Find an empty parking lot, Make right and left turns/circles. Making a left, if the noise get loader, the right side bearing is bad. and vice versa. Do around 10 MPH while turning circles.

Rotors are probably warped and need to be rectified or replaced. When the brakes were replaced did the rotors get turned? If not need to resurface rotors

Replace the right front wheel bearing

Absolutely; wasn't positive until you mentioned the 'hum'. Bad bearings first warning sign is usually the humming noise before the vibration but since you have both, I'd be shocked if it weren't the bearinig, especially since you've got new rotors. In the past, a badly turned or warped rotor would mimic a bad bearing. Best of luck.

Check the front drive axles and boots. A bad cv (constant velocity) joint can cause this.

sounds like you need new brake pads and the rotors atleast turned down if not replaced
the pads should stop the noise and the rotors should stop the vibration/wobble
thanks wes
