I just got the tires rotated and the coolant exchanged. Now there is a grinding noise between fifteen and twenty five mph, it it is louder between eighteen and twenty two mph. The loudest is about twenty to twenty one mph. This has never happened before and the car is kept in good order. It needs the fuel injectors cleaned and pistons as well. But this should not cause the noise. This will help with the fuel usage and other stuff. It sounds like it might be a wheel bearing. I am looking for a second opinion. If I am wrong or maybe I am right.

Either get it into a shop and up on a lift at least one foot off the ground, and spin the rear wheels by hand and listen for the noise. Assuming of course this is a front wheel drive.
Then to listen to the front you will have to start the engine place in gear, then rev the engine up and watch the speedometer as you get around that eighteen and twenty two mph. So you will need two people, one in the drivers seat and one outside listening. Make sure if at first you do not hear the noise in the front is turn the steering wheel left to right also while revving the engine to eighteen and twenty two mph.
