A broken car =]
Are the wheels rubbing on anything?
97 grand am rubbing/grinding noise from right front that is not wheelbearing or brakes
Tire may be rubbing the fender liner especially if the tires are oversized. Can also be a defective wheel bearing.
Sometimes not all the time
Rubbing noises are different for different causes.If the noise is metallic in nature, it might be a brake problem of some sort. If it is not really metallic, it could be a strut, a rubber bushing, a ball joint or tie rod end.Does the noise occur more often when you go over a bump? Making a turn? Applying the brakes?
Most times, the squeaking and rubbing noises are caused by brake pad wear, but you say the brakes are fine. Otherwise, if by constant rotation speed you mean the squeaking/rubbing noise is present even when the brakes are not applied, you might want to get the wheel bearing inspected
water/friction
Maybe that thumping noise is the sound of another car smashing into the rear of your car.
If im right about the noise, its your cv joints. You can tell which one it is on hearing which side its coming from. Well I believe its coming from both sides.however i did change the passenger side cv axle but not the driver side.and it only does it when im making a u turn.
Chances are that your right inner wheel well is rubbing against the tire like it did with my daughters Tribute. Did you have a slight fender bender on your left front bumper? The fenders are plastic and will pop back out and will thereby "fix" your rubbing noise. Check both wheel wells, as well.
Bearings, cv shaft, or brakes.
If you lowered the car or had suspension/strut work done you can be rubbing The body in the boot?
