Hello, I have a 3320 Compact Tractor and the rear axle seal is leaking. I ordered the parts and are on the way to me. I am looking for someone who has done this before. If I take the four bolts out at the end, will the axle just come out? Is there a snap ring that hold it in, and I need to take the transmission casing apart? I have been looking for information or videos online, but I can not find anything. Has anyone replaced the seal before? Can anyone help me out. Thanks Scott
