Is it the wheel bearings

2005 325 I. First issue was a thumping sound that you would hear when turning to the right. Even changing lanes you would hear it. its loder if you turn a corner but you can also hear it just by moving the sterring wheel enough to change lanes on the highway. Now Im starting to hear a roaring sound. It goes up and down with the speed od the car nothe rpm of the motor. any thoughts appreciated.

I had this sound, and thought it was the bearings too. It was the brake caliber rubbing against the hubs due to the pads being worn down. Get this fixed soon or you will have to replace the VERY expensive calibers.

Yep. I know how to do everything with wheels and all but didn't have the equipment to do so. Ended up costing me 600 dollars at Monro for new rear calibers and pads-which does include pad replacement for the life of the vehicle.

Caliper can't rub against the hub, it can rub against the rotor.

OP, if it is indeed a wheel bearing the noise should go away when you turn side to side.

I don't think $44 is VERY expensive.

It should be a slight change to the better, in other words, the rumbling gets better.

Another option is to remove the wheels and spin them by hand. If they are really bad, you can feel/hear it.
