I can start the car runs pretty good. Put it in gear, and as soon as it starts to move I can hear a loud grinding coming from under the car. It happens in both Reverse, and Drive. I checked the rear wheels. Jacked it up, and spun it, and no noise. I jacked up the front, and spun the wheels, and no noise. I will check the front wheel bearings, but they should be fine. I greased them last year. I put in a power rack last year. Could it be that there are loose bolts that might cause that noise?? Otherwise I can't see it rubbing against anything..
