I could not find the center grease zirk for the prop shaft. The owners manual shows a view from above with the center floor section removed of the location. I wondered for a while if they really expected you to either remove the floor or skid plate to access this one fitting that needs attention so often. The access hole through the skid plate was not there so I had to make my own with a hole saw. Anyone else notice this, or am I just lucky? The joint was dry as a bone, btw, another comforting service my former dealer provided.
