Report "snow covered roads. I did notice a slight lull when I went over railroad tracks @ 50 kind of BUMP JUMP. The noise lowered, but when the weight of the vehicle transferred back to the wheels, so did the sound. The noise is constant during accelleration, coasting or braking - and stays constant even with the engine rpm fluctuation... (put it in N going 50, and revved engine. No change in sound. What is the noise, and how can it be repaired?? UPDATE: I put the FWD fuse in, and the noise seems to be a tad quieter, however it still is LOUD at about 40-45mph. Doesnt gain and lose loudness gradually - it appears and disappears almost instantly. Noise stays constant while swerving down the road at "noise speed" so im tending to think it is not the wheel bearings, but in the drivetrain somewhere. Ideas, opinions, suggestions???? Im stumped!! PS - Suggestions have been... driveshaft joint, and Transaxle Output Carrier Bearing(s)"
