CAT 955L Front Idler bushing Replacement?

On Saturday I was looking at the front idler on the old 955L and noticed the idler wasn't aligned in the yoke. In fact the track pads seem to be turning out away from the engine. I then grab a pry bar to see if it was jamb with a large rock or something. What happened next totally took me by surprise. I was able to move the idler back and forth with ease. I check the other side to compare and it was tight. I also looked up the bearing assembly in my little parts book and it is a bushing type I believe. Now I am worried that the axle could be completely broke. I need to get a better look but I think that I may need to pull the track off. Okay so for a backyard mechanic wanting to have some additional fun this weekend, how do I remove the yoke? Obviously I want the easiest and smartest way can I since I have minimal experience.
