2002 FX4 Supercrew: truck has a rythmic sound while driving. Sounds like "whomp, whomp, whomp" and gets faster with speed. Also causes a slight vibration/ grinding feel in the drivers side floor board and in the pedal. Truck has new tires, brakes (ceramic) and rotors. Sound seems to be start around 10 mph. I have been told that my rear axle bearings are making noise, but this was prior to this noise starting. Any ideas? Please?

 

Did the truck make noise before the new tires, brakes and rotors? Always start with the last thing messed with.

 

Yes, it made the noise before. I am having the hardest time finding the source. I am going to put new pads on it hopefully this weekend again. I thought that I had a rotor warped, but now I am wandering if it is the pads.

Any other ideas?

Thanks again for everyones help
