Winding/grinding noise in the front end, not sure what it is?

Your wheel bearings need replaced,just replaced both front ones on my car,Then you will need to have your tires balanced,rotated and front end aligned.Mine was coming from my front driver side,it was loud,replaced,then the passenger side was making a noise,but not as loud,now it is like new.

Check the front brake rotor. When the brake pads wear down too far they will make a grinding noise. I am not sure what sound the axle makes when they begin to wear out. I would check the boot that covers the axle joint for any damage.

Only thin left is the wheel bearings failed or if front wheel drive then a failed cv /s joint. IF the bearings are faulty the grinding noise will be the disc rotor grinding on the caliper . Check out the front end and look for failed ball joints in the suspension.

Assuming that you have already ruled out the brakes, severely worn engine mounts can transmit vibration and noises from the engine which are not normally heard. You don't say in what I see but is the vehicle two or four wheel drive. Since you mention CV half shafts I have to assume it is at least front wheel drive. If the vehicle is four wheel drive then there is a front differential with bearings in it that may be at fault. Have you done both sides when you say "hub assembly". Defective hub bearings will make grinding noises which will change tone or intensity when turning, accelerating or braking however the noise is usually fairly constant unless they are only just starting to fail. CV joints don't normally "grind" unless they are really bad. They usually make progressively worse "clicking" sounds or "clunking" sounds especially when turning hard, changing gears or direction of travel (forward to reverse and back again). Do you have non-stock tires/wheels? Larger/wider than factory spec tire sizes can rub the fender wells when the car is moving or turning. Another thing it could possibly be is the air dam below the front bumper. If it is loose it will push down in the airstream while the car is moving and rub on the ground.

On my car, it was a stuck brake caliper.

since this is a front wheel drive car i wouldnt really advise doing this by yourself unless youv done stuff like that before. I would say its not so much difficult as it is tedious work and requires some time to complete.

Have a 4 wheel alignment done and have them check the wheel bearings.

its your left wheel bearing, or the cv axle.. good luck keith...

its the bearing in the differential i'm affraid you can temperarily quieten the noise by spraying loads of lube into it but a new bearing (if not a seald diff) is a most definate
