M4A3 105 Track No-Clip

Has anyone else noticed how the American M4A3 105 front half of the tracks tend to dip down into the ground when you reach 30kph or so. It tends to mess with the barrel depression on the move and prevents you from getting over small rocks or ridges. I do not have any images of this at the moment but if necessary I can. Thank you, if you have any further questions please comment!
