The noise is only in FWD moving for wards or back. Flat, up or down hill. Really loud on down hill. No wire. I can't jack up the front end and move the wheel as all wheels turn together.
The 4400 Utility has a shaft that goes from the main drive to each wheels so that the ground clearance is higher. This gives extra bearing and gears but it does not sound like a bearing noise.
Thanks, Stubut.
