I just noticed some oil leaking from my left rear wheel (sitting in the machine left) So I removed the wheel and noticed some end-play, the hub could be pushed in and out. No up and down or side to side, just in and out. I have looked at the parts diagram and they mention a washer, bobcat # 6592765 that will take out the end play. Is this what I need to do? How hard of a job is this, I figured I would replace the bearings (inner outer)/seal also. Does anyone have any directions/pictures on how to do this job (mainly how to get into the chain case). Thanks
