Are the transfer case mounts supposed to flex? My rear end feels like it drops when I stop. It also does this when I hit the gas and brake at the same time (kind of like power braking). I thought it was axle wrap, but the axle isn't moving at all. I looked at my transfer case and the mount flexes. I dont know if this is the problem or not, so if you have any other suggestions please let me know. Thanks!!
