It almost sounds like a brake issue --- do you notice a change in sound when you brake ? there could also be a issue in the rear differential ( gears and bearings ).
the one thing that I would check is the wheel bearings themselves -- if the bearing pack has split, what you are hearing is the little metal pieces grinding around and around as the wheel spins -- if this is the problem then I hate to be the one to tell you that it is not good news, those little pieces of metal can grind away at the smooth surface making it very hard to fit in a new bearing. I take it that it is not leaking gear oil anywhere (?) so the seal is still good ( if there is in fact gear oil still in the rear diffy ). to check what wheel the sound is coming from just jack up the wheel(s) and spin them by hand and feel / hear the problem. ( when spinning the tires this way -- make sure you block up the front tires and put the car in neutral,, e-brake off,on level ground ),, it should be very clear at that point where the sound is coming from. one other thing you can try real quick before jacking up the wheels is to drive somewhere and feel the wheel ( the center ) and see if it is hot or warm,, this is a sign of metal on metal friction. and staying on the bad bearing issue -- it just might be one of many neddle bearings going bad, better to fix it sooner than later. with the idea of something wrong with the brakes -- when brake pads/shoes are getting worn out they will make a loud squealling noise to let you know that it is time to replace them. if you don't want to get your hands to dirty there are brake shops in just about every corner of the US that offer a FREE brake inspection -- this might be the best way to go to pin point the problem,, for one, it is free and you can find out exactly what the problem is and then go home and fix it yourself -- or just pay the nice people the 75 bucks to swap them out then and there ( life time warranty ) and 35 minutes later you would be down the road. but look into it soon -- it could cost a heep more if some heavy damage is done.
if you do run some test yourself -- feel free to e-mail me back and we can narrow it down in a short period of time,, I am happy to help, have a great day,

Why do I hear grinding noises while driving?

Hit in the rear axle may have damaged bearings or brake parts. Jack up the side you hear noise from, put on stand, then have helper rotate wheel while you look underneath and listen to see where noise is coming from. Use length of old fuel or heater hose, one end in ear, to locate exactly where noise comes from.

There is a grinding noise from the front of the vehicle while driving. All new brakes. The wheel bearings have been checked and are fine.

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.

Grinding noise when cornering

If your vehicle has front wheel drive you have to inspect the outer CV boots on the drive axles. If they are ripped then they are probably the culprit for the noise. Check the side that sounds like the noise is cominf from.

2004 dodge intrepid front end noise

Without a description of the noise, this is impossible to diagnose. Common problem with these vehicles is a "grinding" type noise. This will be a bearing that has gone bad or brake pads that are beyond the service life (louder screeching or grinding upon braking). Popping noises are the CV drive axles are bad (noise is typically louder when when the vehicle is in motion and turning).

52 grinding noise from under car . not sure if it

Hi, When a grinding noise is detected first locate the area of the car it is being generated from. Most grinding noises will be being generated while driving, if you are having a hard time detecting the location of the grinding sound, have a helper ride along in the rear seat to give a new perspective on the origin of the grinding noise. A grinding noise can be generated by many things from worn out brake pads to axle bearing failure. Once a grinding sound has been detected action must be prompt. Grinding in most cases is telling you something has failed or is failing. It can be as a result of worn out brake pads or shoes, check your engine and transmission mount, check for axle bearing failure, check your power steering system for leak...
Take care
