Hi all. Got a final drive question since I don't own a service manual YET. I just replaced an oil seal on what I believe I am correct in calling the final drive (the rear axle runs through it). I have an '04 Rancher 350es 2 wheel drive. What type of oil do I replace and how much? I am assuming it fills from the top until it starts running out the "oil check bolt". Any help is greatly appreciated.
