When I shift my truck in 4 x 4 there is a grinding noise from the right front wheel. had the brakes and rotors replaced, and the whell bearing on that side replaced. The grinding is only in 4 x 4 and it seems that the front right tire is not turning when it is in four wheel drive. put it on jacks and engaged the 4 wheel drive and no front tire turning on right side? help

A grinding or rumbling noise can also be symptoms of a wheel bearing or constant velocity joint in a driveshaft. A worn wheel bearing can also cause a 'whistling' sound (as can a worn CV joint).
A grinding noise with brakes is either worn pads causing metal to metal contact on the brake disk/rotor, or the brake backing plate catching on a spinning rotor ... or a loose/missing anti squeal brake shim (they stop the pads from rattling and vibrating).
However, as you say a mechanic has looked at the brakes and can't find anything wrong .. I think I would begin to suspect a wheel bearing or constant velocity joint on the driveshaft (front wheel drive cars).
ok, think about mass that moves under the forces of braking, things like engines and gearboxes, have you checked all those mounts for integrity, have a look to see if anything has been rubbing, new shiney spots appearing that weren't there before.
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.
Hello i would check your wheel bearings or sometimes called bearing hub .Jack car up prop the car with axle stands now remove your tires and rotors once removed wiggle you bearing hub left to the right your bearing hub should have minimal play one side to the other is obvious the looser play hub will be your noise you have been experiencing.most people call this road noise.
Does it happen all the time or when brakes are applied? Usally a bad bearing will cause a growling noise. I would check both the brake pads on the right side. Often the inner pad will wear off, then you have metal against metal, causing a grinding noise.
when turning left vehicle distributes weight to right front wheel bearing causing load. since u describe a noise in right front while driving straight i would suspect failed right front wheel bearing. see if your noise changes/goes away while turning right that should tell u 4 sure
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.
