I did my first oil change on my Pro. When I went to put the front bolts back to remount the skid plate I found one bolt kept spinning. Upon inspection saw that they have a nut up inside the frame that the bolt tightens to that was either glued or tacked somehow and came off. You can NOT get to the nut! I pushed it over to the hole with a piece of wire but now what? As soon as you touch it with the bolt it will just move away again. Am not happy......
