I have a M7060HDC12 and after the fluid in the front axle warms up the right side make a gurgling noise when you make a sharp turn. I have drained the fluid from both axles and the front differential and refilled. I got just over 2 gallons total out and was only able to get about the same amount back in. I drove it around for 5 minutes and could not get anymore in. I then drove for another 10 minutes and got almost another quart in so it is about 3 quarts low from what the owners manual said it would take to fill it up. After all of this it is still making the same noise when make a sharp turn. Any help is appreciated.
